The build process of nessus-core-2.2.9-r1 tries to run the pcap-config script. This script was introduced in libpcap 1.0.0. However, nessus-core-2.2.9-r1 does not depend on >=net-libs/libpcap-1.0.0. Reproducible: Always Steps to Reproduce: 1. emerge '=libpcap-0.9.8' 2. echo net-analyzer/nessus-core >> /etc/portage/package.keywords 3. emerge '=nessus-core-2.2.9-r1' Actual Results: The build process yields: i686-pc-linux-gnu-gcc -Wl,-O1 -Wl,--as-needed `sh ./cflags` nessus-check-signature.o -o nessus-check-signature `/usr/bin/nasl-config --libs` `/usr/bin/nessus-config --libs` -ldl -lwrap `pcap-config --libs` /bin/sh: pcap-config: command not found /usr/lib/libnessus.so: undefined reference to `pcap_close' /usr/lib/libnessus.so: undefined reference to `pcap_perror' /usr/lib/libnessus.so: undefined reference to `pcap_open_live' /usr/lib/libnessus.so: undefined reference to `pcap_compile' /usr/lib/libnessus.so: undefined reference to `pcap_lookupnet' /usr/lib/libnessus.so: undefined reference to `pcap_datalink' /usr/lib/libnessus.so: undefined reference to `pcap_setfilter' /usr/lib/libnessus.so: undefined reference to `pcap_lookupdev' /usr/lib/libnessus.so: undefined reference to `pcap_next' collect2: ld returned 1 exit status make[1]: *** [nessus-check-signature] Error 1 Expected Results: The ebuild should compile without errors. Upgrading to libpcap >= 1.0 fixes the problem. emerge --info Portage 2.1.9.42 (default/linux/x86/10.0, gcc-4.3.2, glibc-2.9_p20081201-r2, 2.6.34-ck i686) ================================================================= System uname: Linux-2.6.34-ck-i686-Intel-R-_Pentium-R-_M_processor_1.73GHz-with-gentoo-2.0.2 Timestamp of tree: Thu, 23 Jun 2011 15:15:01 +0000 app-shells/bash: 4.1_p9 dev-java/java-config: 2.1.11-r3 dev-lang/python: 2.4.6, 2.6.5-r2, 3.2 dev-util/cmake: 2.8.1-r2 sys-apps/baselayout: 2.0.2 sys-apps/openrc: 0.8.2-r1 sys-apps/sandbox: 1.6-r2 sys-devel/autoconf: 2.13::<unknown repository>, 2.65-r1 sys-devel/automake: 1.4_p6::<unknown repository>, 1.5::<unknown repository>, 1.6.3::<unknown repository>, 1.7.9-r1::<unknown repository>, 1.8.5-r3::<unknown repository>, 1.9.6-r2::<unknown repository>, 1.10.2, 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 3.4.6-r2, 4.3.2-r3 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6b sys-devel/make: 3.81::<unknown repository> sys-kernel/linux-headers: 2.6.36.1 sys-libs/glibc: 2.9_p20081201-r2 virtual/os-headers: 2.6.36.1 (sys-kernel/linux-headers) ACCEPT_KEYWORDS="x86" ACCEPT_LICENSE="* -@EULA" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=i686 -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-O2 -march=i686 -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs distlocks fixlafiles fixpackages news parallel-fetch protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="de_DE.utf8" LC_ALL="C" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="de" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/lib/layman/gnome /var/lib/layman/pro-audio /var/lib/layman/sunrise /var/lib/layman/dotnet /var/lib/layman/thelinux /var/lib/layman/haskell /var/lib/layman/moonrise /var/lib/layman/bitcoin /usr/local/portage" SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" USE="X a52 aac aalib acl alsa apache2 apm berkdb bzip2 cairo cddb cdparanoia cli cracklib crypt cxx dbus dri dvd expat ffmpeg fftw flac fluidsynth fortran gdbm gphoto2 gpm gtk gtk2 hbci iconv ipv6 jack jpeg kqemu ladspa lcms matroska mmx modules mp3 mpeg mplayer mudflap ncurses nls nptl nptlonly ogg opengl openmp pam pcre pdf png pppd python qt3support readline sdl session speex sqlite ssl svg sysfs tcpd theora threads tidy tiff unicode unix98 vhosts vorbis win32codecs x86 xcomposite xml xorg xv xvid zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="authz_host auth_basic authn_file auth_dbm auth_anon auth_digest alias file-cache echo charset-lite cache disk-cache mem-cache ext-filter case_filter case-filter-in deflate filter mime-magic cern-meta expires headers usertrack unique-id proxy proxy-connect proxy-ftp proxy-http info include cgi cgid dav dav-fs vhost-alias speling rewrite log_config logio env setenvif mime status autoindex asis negotiation dir imap actions userdir so" CALLIGRA_FEATURES="braindump flow karbon kexi kpresenter krita tables words" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="de" PHP_TARGETS="php5-3" QEMU_SOFTMMU_TARGETS="i386 m68k ppc ppc64 x86_64" QEMU_USER_TARGETS="i386 m68k ppc ppc64 x86_64" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="intel" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, MAKEOPTS, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Please attach a full build log. Also, the problem looks more like you compiled nessus-libraries (the package that actually requires libpcap) with a newer version of libpcap, then downgraded libpcap causing the libnessus.so library to break, then tried to compile nessus-core against the broken library causing the failure you posted.
And <net-libs/libpcap-1.0.0 was recently removed from the tree too so closing.
