configure fails with checking for Qt... configure: error: Qt (>= Qt 3.3) (library qt) not found. Please check your installation! looking at the config.log, it seems the configure actually found the right path (which happen to be /usr/qt/3.svn/ on my system), but failed to link because it used -lqt instead of -lqt-mt as is usually the case with qt (multi-threaded) orzel@berlioz portage/sci-astronomy/celestia% emerge --info Portage 2.1.1_rc1-r1 (default-linux/amd64/2005.1, gcc-4.0.3/amd64-vanilla, glibc-2.4-r3, 2.6.16.14 x86_64) ================================================================= System uname: 2.6.16.14 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ Gentoo Base System version 1.12.4 Last Sync: Mon, 28 Aug 2006 15:50:01 +0000 ccache version 2.4 [disabled] app-admin/eselect-compiler: 2.0.0_rc1-r6 dev-lang/python: 2.3.5, 2.4.3-r2 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.4-r2 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.18.1 sys-devel/autoconf: 2.13, 2.60 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2 sys-devel/binutils: 2.17 sys-devel/gcc-config: 1.3.13-r3 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.16 ACCEPT_KEYWORDS="amd64 ~amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=k8 -O3 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.svn/share/config /usr/kde/4.svn/share/config /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/eselect/compiler /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c" CXXFLAGS="-march=k8 -O3 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="ftp://ftp.ipv6.uni-muenster.de/pub/linux/distributions/gentoo http://ftp-stud.fht-esslingen.de/pub/Mirrors/gentoo/ ftp://194.117.143.70/mirrors/gentoo http://ftp.snt.utwente.nl/pub/os/linux/gentoo ftp://linux.rz.ruhr-uni-bochum.de/gentoo-mirror/ http://194.117.143.71 http://ftp6.uni-erlangen.de/pub/mirrors/gentoo" LINGUAS="fr it" MAKEOPTS="-j 3" 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'" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/portage-fh" SYNC="rsync://gentoo.freehackers.org/gentoo-portage" USE="amd64 X a52 aac alsa arts avi berkdb bidi bitmap-fonts browserplugin cairo cdda cdio cli crypt cups dga divx4linux dlloader dri dts dv dvb dvd dvdread edl eds elibc_glibc emboss encode exif fbcon fbdev ffmpeg flac font-server foomaticdb fortran freetype gif gnome gnutls gpm gstreamer gtk gtk2 httpd imap imlib innodb input_devices_keyboard input_devices_mouse ipv6 isdnlog java jpeg kde kernel_linux linguas_fr linguas_it live lzw lzw-tiff mad matroska mozilla mp3 mpeg ncurses nls nptl nptlonly nsplugin nvidia ogg oggvorbis opengl pam pcre pdflib perl perlsuid pic png pppd python qt3 qt4 quicktime readline reflection rtc sasl sdl session speex spell spl sqlite3 ssl stream svg tcpd theora tiff truetype truetype-fonts type1-fonts unicode usb userland_GNU v4l v4l2 vcd video_cards_vesa video_cards_vga vlm vorbis wifi wxwindows xinerama xorg xpm xv xvid xvmc zlib" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, PORTAGE_RSYNC_EXTRA_OPTS
