If your system doesn't have gnu bison installed than emerging iproute2 will end with crash, because it requires gnu bison. Also it may need dev-util/yacc, because i had to manually install it before. (emerge net-libs/libpcap-1.1.1 failed without yacc, but it hadn't required it) Reproducible: Always Steps to Reproduce: 1. # emerge -avt sys-apps/iproute2 Actual Results: ... make[1]: bison: Command not found make[1]: *** [emp_ematch.yacc.c] Error 127 make[1]: Leaving directory `/var/tmp/portage/sys-apps/iproute2-2.6.35-r2/work/iproute2-2.6.35/tc' make: *** [all] Error 2 emake failed * ERROR: sys-apps/iproute2-2.6.35-r2 failed (compile phase): * (no error message) * * Call stack: * ebuild.sh, line 56: Called src_compile * environment, line 2460: Called die * The specific snippet of code: * emake CC="$(tc-getCC)" HOSTCC="$(tc-getBUILD_CC)" AR="$(tc-getAR)" || die Expected Results: successful compilation USE="-X -kde4 -kde -qt -gnome -gtk2 -gtk cups niash gutenrpint sane mysql apache2 unicode nls cyrillic wifi aac mp3 flac -hal amr alsa aalib a52 audio audiofile cgi dhcp dhcpcd curl faad sql theora gd pptp" # emerge --info Portage 2.1.10.3 (default/linux/x86/10.0, gcc-4.4.5, glibc-2.12.2-r0, 2.6.30-gentoo-r8 i686) ================================================================= System uname: Linux-2.6.30-gentoo-r8-i686-AMD_Sempron-tm-_2600+-with-gentoo-2.0.3 Timestamp of tree: Sun, 31 Jul 2011 00:45:01 +0000 app-shells/bash: 4.1_p9 dev-lang/python: 2.7.1-r1, 3.1.3-r1 sys-apps/baselayout: 2.0.3 sys-apps/openrc: 0.8.3-r1 sys-apps/sandbox: 2.4 sys-devel/autoconf: 2.68 sys-devel/automake: 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.4.5 sys-devel/gcc-config: 1.4.1-r1 sys-devel/libtool: 2.2.10 sys-devel/make: 3.82 sys-kernel/linux-headers: 2.6.36.1 (virtual/os-headers) sys-libs/glibc: 2.12.2 Repositories: gentoo ACCEPT_KEYWORDS="x86" ACCEPT_LICENSE="* -@EULA" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=i686 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/gconf /etc/gentoo-release /etc/sandbox.d /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-O2 -march=i686 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs distlocks ebuild-locks fixlafiles fixpackages news parallel-fetch protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="" GENTOO_MIRRORS="ftp://gentoo.kiev.ua/ http://gentoo.iteam.net.ua/ http://gentoo.kiev.ua/ftp/ " LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="ru" MAKEOPTS="-j1" 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="" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="a52 aac aalib acl alsa amr apache2 audio audiofile berkdb bzip2 cgi cli cracklib crypt cups curl cxx cyrillic dhcp dhcpcd dri faad flac fortran gd gdbm gpm gutenrpint iconv ipv6 modules mp3 mudflap mysql ncurses niash nls nptl nptlonly openmp pam pcre perl pppd pptp python readline sane session sql ssl sysfs tcpd theora unicode wifi x86 xorg zlib" ALSA_CARDS="i8x0" 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="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" 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" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="ru" PHP_TARGETS="php5-3" RUBY_TARGETS="ruby18" SANE_BACKENDS="niash" USERLAND="GNU" VIDEO_CARDS="nvidia" 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, LANG, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
