安装IBUS中文输入法遇到了问题，设置了环境变量后仍然无法在想谷歌浏览器等GTK程序中调用输入法，GOOGLE了一番，终于找到了原因。
原来是自己的自己的make文件的设置为
# These settings were set by the catalyst build script that automatically # built this stage. # Please consult /usr/share/portage/config/make.conf.example for a more # detailed example. CFLAGS="-O2 -march=nocona -pipe" CXXFLAGS="${CFLAGS}" # WARNING: Changing your CHOST is not something that should be done lightly. # Please consult before changing. CHOST="i686-pc-linux-gnu" MAKEOPTS="-j3" USE="-gnome3 qt3 qt4 gtk -kde alsa cdr" GENTOO_MIRRORS="http://mirrors.sohu.com/gentoo"#SYNC="rsync://mirrors.stuhome.net/gentoo-portage"LINGUAS="zh_CN us"
将GTK标记给USE去掉了，将USE更改为USE="-gnome3 qt3 qt4 gtk kde alsa cdr"
执行
emerge --info
输出结果如下Portage 2.1.10.11 (default/linux/x86/10.0/desktop/kde, gcc-4.5.3, glibc-2.12.2-r0, 3.0.6-gentoo i686) ================================================================= System uname: Linux-3.0.6-gentoo-i686-Intel-R-_Pentium-R-_Dual_CPU_T2370_@_1.73GHz-with-gentoo-2.0.3 Timestamp of tree: Fri, 02 Dec 2011 10:00:01 +0000 app-shells/bash: 4.1_p9 dev-lang/Python: 2.7.2-r3, 3.1.4-r3 dev-util/cmake: 2.8.6-r4 dev-util/pkgconfig: 0.26 sys-apps/baselayout: 2.0.3 sys-apps/openrc: 0.9.4 sys-apps/sandbox: 2.5 sys-devel/autoconf: 2.68 sys-devel/automake: 1.11.1 sys-devel/binutils: 2.21.1-r1 sys-devel/gcc: 4.5.3-r1 sys-devel/gcc-config: 1.4.1-r1 sys-devel/libtool: 2.4-r1 sys-devel/make: 3.82-r1 sys-kernel/linux-headers: 2.6.39 (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=nocona -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/config /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -march=nocona -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="http://mirrors.sohu.com/gentoo" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="zh_CN us" MAKEOPTS="-j3" 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.gentoo.org/gentoo-portage" USE="X a52 aac acl acpi alsa berkdb bluetooth branding bzip2 cairo cdda cdr cli consolekit cracklib crypt cups cxx dbus declarative dri dts dvd dvdr emboss encode exif fam firefox flac fortran gdbm gdu gif gpm gtk iconv ipv6 jpeg kde kipi lcms ldap libnotify mad mng modules mp3 mp4 mpeg mudflap ncurses nls nptl nptlonly ogg opengl openmp pam pango pcre pdf phonon plasma png policykit ppds pppd qt3 qt3support qt4 readline sdl semantic-desktop session spell ssl startup-notification svg sysfs tcpd tiff truetype udev unicode usb vorbis x264 x86 xcb xcomposite xinerama xml xorg xscreensaver xulrunner xv xvid 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 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="kexi words flow plan 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 evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="zh_CN us" PHP_TARGETS="php5-3" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga neomagic nouveau nv r128 radeon savage sis tdfx trident vesa via vmware dummy v4l" 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
重新emerge -1 ibus然后重启浏览器，ok！
