cdrkit links against libcap (if present), but doesn't appear to be in RDEPEND. Thus, when merging binary packages, the library is missing and cdrkit (at least /usr/bin/wodim) is going to complain about it: $ /usr/bin/wodim /usr/bin/wodim: error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory Portage 2.1.3.6 (hardened/x86/2.6, gcc-4.1.2-vanilla, glibc-2.6.1-r0, 2.6.22-hardened i686) ================================================================= System uname: 2.6.22-hardened i686 Intel(R) Pentium(R) M processor 2.00GHz Gentoo Base System release 2.0.0_rc2 Timestamp of tree: Sun, 19 Aug 2007 08:20:01 +0000 dev-lang/python: 2.5.1-r2 dev-python/pycrypto: 2.0.1-r6 sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.61-r1 sys-devel/automake: 1.7.9-r1, 1.9.6-r2, 1.10 sys-devel/binutils: 2.17-r1 sys-devel/gcc-config: 1.4.0 sys-devel/libtool: 1.5.24 virtual/os-headers: 2.6.22-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -pipe -march=i686 -g -ggdb2" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-O2 -pipe -march=i686 -g -ggdb2" DISTDIR="/usr/portage/distfiles" FEATURES="buildpkg collision-protect cvs distclean distlocks metadata-transfer sandbox sfperms sign splitdebug strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.barfoo.org http://mirrors.sec.informatik.tu-darmstadt.de/gentoo http://distfiles.gentoo.org" INSTALL_MASK="/usr/share/gtk-doc /usr/kde/*/share/doc /usr/share/doc /usr/lib/debug /etc/cron.* /etc/logrotate.d /etc/xinet.d" LANG="C" LC_ALL="C" LDFLAGS="-Wl,-z,now -Wl,--sort-common" MAKEOPTS="-j8" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.barfoo.org/gentoo-portage" USE="berkdb cracklib crypt hardened midi ncurses nptl nptlonly offensive pam perl pic python readline ssl urandom x86 xorg zlib" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" USERLAND="GNU" VIDEO_CARDS="radeon" Unset: CTARGET, EMERGE_DEFAULT_OPTS, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY
