On my stable x86 system, the new dev-java/commons-compress-1.4.1 has a requirement for dev-java/xz-java-1.0::gentoo - which is ~x86 and has no stable version. This blocks the entire 'emerge -uDN world' update. emerge -uDvN --keep-going world && revdep-rebuild These are the packages that would be merged, in order: Calculating dependencies... done! Total: 0 packages, Size of downloads: 0 kB !!! The following update has been skipped due to unsatisfied dependencies: dev-java/commons-compress:0 !!! All ebuilds that could satisfy "dev-java/xz-java" have been masked. !!! One of the following masked packages is required to complete your request: - dev-java/xz-java-1.0::gentoo (masked by: ~x86 keyword) (dependency required by "dev-java/commons-compress-1.4.1" [ebuild]) For more information, see the MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. Temporary workaround is to add the line dev-java/xz-java ~x86 to the /etc/portage/package.keywords file, but this pollutes my intention to have a purely 'stable' system emerge --info Portage 2.1.10.49 (hardened/linux/x86, gcc-4.5.3, glibc-2.14.1-r3, 3.4.0-gentoo i686) ================================================================= System uname: Linux-3.4.0-gentoo-i686-AMD_E-300_APU_with_Radeon-tm-_HD_Graphics-with-gentoo-2.1 Timestamp of tree: Sun, 03 Jun 2012 23:35:01 +0000 app-shells/bash: 4.2_p20 dev-java/java-config: 2.1.11-r3 dev-lang/python: 2.4.6, 2.5.4-r4, 2.7.3-r1, 3.1.5, 3.2.3 dev-util/cmake: 2.8.7-r5 dev-util/pkgconfig: 0.26 sys-apps/baselayout: 2.1-r1 sys-apps/openrc: 0.9.8.4 sys-apps/sandbox: 2.5 sys-devel/autoconf: 2.13, 2.68 sys-devel/automake: 1.9.6-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.21.1-r1 sys-devel/gcc: 4.3.6-r1, 4.4.6-r1, 4.5.3-r2 sys-devel/gcc-config: 1.5-r2 sys-devel/libtool: 2.4-r1 sys-devel/make: 3.82-r1 sys-kernel/linux-headers: 3.1 (virtual/os-headers) sys-libs/glibc: 2.14.1-r3 Repositories: gentoo zugaina x-portage ACCEPT_KEYWORDS="x86" ACCEPT_LICENSE="*" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=i686 -O2 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/config /usr/share/gnupg/qualified.txt /usr/share/maven-bin-2.2/conf" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/dconf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5.3/ext-active/ /etc/php/cgi-php5.3/ext-active/ /etc/php/cli-php5.3/ext-active/ /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="-march=i686 -O2 -pipe" DISTDIR="/usr/portage/distfiles" EMERGE_DEFAULT_OPTS="--autounmask=n" FEATURES="assume-digests binpkg-logs distlocks ebuild-locks fixlafiles news parallel-fetch protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="" GENTOO_MIRRORS="http://distfiles.gentoo.org" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j1" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/lib/layman/zugaina /usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X accessibility arts bash-completion berkdb bzip2 cli consolekit cracklib crypt cups cxx dbus device-mapper dri examples extras fam fontconfig gdbm gnome gpm hardened iconv idea imap java jpeg lm_sensors maildir modperl modules mudflap mysql ncurses nls nptl nsplugin odbc ogg opengl openmp pam pax_kernel pcre pdf php pic png pnp policykit postgres pppd qt3support readline samba sasl session source ssl tcpd tk udev unicode urandom vhosts vorbis wmf x86 xorg xpm 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="actions alias auth_basic auth_digest authn_anon authn_dbd 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 dbd deflate dir disk_cache env expires ext_filter file_cache filter headers ident imagemap include info log_config logio mem_cache mime mime_magic negotiation proxy proxy_ajp proxy_balancer proxy_connect proxy_http rewrite setenvif so speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump" 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" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" PHP_TARGETS="php5-3" PYTHON_TARGETS="python3_2 python2_7" RUBY_TARGETS="ruby18 ruby19" USERLAND="GNU" VIDEO_CARDS="vesa vmware fbdev" 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, INSTALL_MASK, LANG, LC_ALL, LINGUAS, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON
dev-java/commons-compress-1.4.1 is ~x86 as well. So accept ~x86 keyword for both or don't for commons-compress.
