It seems that gdm jpeg loader (libpixbufloader-jpeg.so) requires libjpeg.so.62 library. But that doesnt exist after emerging media-libs/jpeg-7. Emerging media-libs/jpeg-compat fixes that but it should work out-of-the-box. # ldd /usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jpeg.so linux-gate.so.1 => (0xffffe000) libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb7ecf000) libgdk_pixbuf-2.0.so.0 => /usr/lib/libgdk_pixbuf-2.0.so.0 (0xb7eb5000) libgio-2.0.so.0 => /usr/lib/libgio-2.0.so.0 (0xb7e49000) libgobject-2.0.so.0 => /usr/lib/libgobject-2.0.so.0 (0xb7e0c000) libgmodule-2.0.so.0 => /usr/lib/libgmodule-2.0.so.0 (0xb7e06000) libdl.so.2 => /lib/libdl.so.2 (0xb7e02000) libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0xb7d29000) libm.so.6 => /lib/libm.so.6 (0xb7d03000) libc.so.6 => /lib/libc.so.6 (0xb7bb9000) /lib/ld-linux.so.2 (0xb7f19000) Reproducible: Didn't try Steps to Reproduce: Assume gnome-base/gdm emerged. 1. unmerge media-libs/jpeg-compat 2. emerge media-libs/jpeg-7 3. configure GDM to use some theme containing jpeg image # emerge --info Portage 2.1.6.13 (default/linux/x86/2008.0, gcc-4.3.4, glibc-2.10.1-r0, 2.6.30-gentoo-r5 i686) ================================================================= System uname: Linux-2.6.30-gentoo-r5-i686-Intel-R-_Core-TM-2_Duo_CPU_T5800_@_2.00GHz-with-gentoo-2.0.1 Timestamp of tree: Wed, 26 Aug 2009 14:00:01 +0000 ccache version 2.4 [enabled] app-shells/bash: 4.0_p28 dev-java/java-config: 2.1.8-r1 dev-lang/python: 2.6.2-r1 dev-util/ccache: 2.4-r8 dev-util/cmake: 2.6.4-r2 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.4.3-r3 sys-apps/sandbox: 2.0 sys-devel/autoconf: 2.13, 2.63-r1 sys-devel/automake: 1.4_p6, 1.5, 1.7.9-r1, 1.9.6-r2, 1.10.2, 1.11 sys-devel/binutils: 2.19.1-r1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.30-r1 ACCEPT_KEYWORDS="x86 ~x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -mtune=core2 -march=core2 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/config /var/bind /var/spool/torque" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/eselect/postgresql /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/udev/rules.d" CXXFLAGS="-O2 -mtune=core2 -march=core2 -pipe" DISTDIR="/home/portage/distfiles" FEATURES="ccache distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="cs_CZ.UTF-8" LC_ALL="cs_CZ.UTF-8" LDFLAGS="-Wl,-O1" LINGUAS="cs en" MAKEOPTS="-j4" PKGDIR="/home/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="/home/portage/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY=" " SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acl acpi alsa bash-completion berkdb bzip2 cli cracklib crypt cups dbus dri fortran gdbm gnutls gpm iconv isdnlog mmx mudflap ncurses nls nptl nptlonly openal opengl openmp pam pch pcre perl pppd python qt3support readline reflection session smp spl sse sse2 ssl ssse3 sysfs tcpd truetype unicode vim-syntax win32codecs x86 xorg zlib" ALSA_CARDS="hda-intel" 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 synaptics" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="cs en" USERLAND="GNU" VIDEO_CARDS="nvidia vesa nv" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Please use revdep-rebuild to remerge broken packages. jpeg-compat should only be used for binary apps. Thanks
