emboss-4.0.0 depends on several other packages, all of which can be compiled with the EMBOSS use flag. When compiling emboss this flag is not set for those. Reproducible: Always Steps to Reproduce: emerge emboss, like so # emerge -pv emboss Actual Results: The emboss ebuild does not set the EMBOSS use flag for its dependencies Expected Results: The emboss ebuild should set the EMBOSS use flag for its dependencies emerge --info Portage 2.1.6.11 (default/linux/amd64/2008.0, gcc-4.3.2, glibc-2.8_p20080602-r1, 2.6.27-gentoo-r8 x86_64) ================================================================= System uname: Linux-2.6.27-gentoo-r8-x86_64-AMD_Phenom-tm-_9850_Quad-Core_Processor-with-glibc2.2.5 Timestamp of tree: Thu, 14 May 2009 18:15:03 +0000 app-shells/bash: 3.2_p39 dev-java/java-config: 2.1.7 dev-lang/python: 2.5.4-r2 sys-apps/baselayout: 1.12.11.1 sys-apps/sandbox: 1.6-r2 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="amd64" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=k8 -msse3" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-O2 -pipe -march=k8 -msse3" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="ftp://gentoo.cites.uiuc.edu/pub/gentoo" LDFLAGS="-Wl,-O1" MAKEOPTS="-j5" 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" SYNC="rsync://rsync.namerica.gentoo.org/gentoo-portage" USE="X acl amd64 berkdb bzip2 caps cli cracklib crypt cups dbus dri fortran gdbm gpm hal iconv isdnlog java jpeg midi mmx mudflap multilib ncurses nls nptl nptlonly nsplugin opengl openmp pam pcre perl png pppd python readline reflection session spl sse sse2 ssl startup-notification symlink sysfs tcpd tiff tk truetype unicode xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci 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="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 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" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="vesa fglrx" # emerge -pv emboss These are the packages that would be merged, in order: Calculating dependencies... done!

The packages you list are not dependencies of emboss. They can use emboss if you want them to use it. If you want his, _you_ have to enable the useflags for the listed packages.
