In src_unpack there is a warning that says the testsuite will be disabled because the tcltk USE flag isn't set. It doesn't actually disable the tests though, so the emerge fails during src_test with lots of Tcl_* undefined reference ld errors.
Strange. It works for me and the ebuild looks ok. emerge --info please
Hmm. I can't reproduce it either, any more. Sorry about that. :-S emerge --info, on the offchance it might be useful anyway: Portage 2.1_rc1-r2 (default-linux/amd64/2006.0, gcc-3.4.6, glibc-2.4-r1, 2.6.16-gentoo-r3 x86_64) ================================================================= System uname: 2.6.16-gentoo-r3 x86_64 AMD Athlon(tm) 64 Processor 3200+ Gentoo Base System version 1.12.0_pre19 dev-lang/python: 2.3.5-r2, 2.4.3-r1 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: [Not Present] dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 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: 2.16.1-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r3 ACCEPT_KEYWORDS="amd64 ~amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=athlon64 -O2 -pipe -fno-ident" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/kde/3/share/config /usr/share/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/eselect/compiler /etc/gconf /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/env.d" CXXFLAGS="-march=athlon64 -O2 -pipe -fno-ident" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks sandbox sfperms splitdebug strict test userpriv usersandbox" GENTOO_MIRRORS="http://gentoo.blueyonder.co.uk http://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo/ http://ftp.heanet.ie/pub/gentoo/ http://pandemonium.tiscali.de/pub/gentoo/" LANG="en_GB.UTF-8" LC_ALL="en_GB.UTF-8" LDFLAGS="-Wl,-O1" LINGUAS="en_GB" MAKEOPTS="-j2" 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/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 X alsa audiofile berkdb bitmap-fonts bzip2 cairo cdparanoia cdr chroot crypt ctype curl dri dvd dvdr dvdread emul-linux-x86 encode exif expat fam ffmpeg firefox flac ftp gd gdbm gif glut gpm gtk gtk2 iconv imlib jpeg jpeg2k kqemu lesstif libwww mad maildir mbox mng mono mp3 mpeg msn musepack ncurses nls nptl offensive ogg oggvorbis opengl pam pam_chroot pcre pdflib php png python readline sdl spell ssl svg tcpd tetex threads truetype truetype-fonts type1-fonts udev unicode usb userlocales vorbis xml2 xpm xv xvid zlib elibc_glibc input_devices_keyboard input_devices_mouse kernel_linux linguas_en_GB userland_GNU video_cards_radeon video_cards_vesa video_cards_fbdev" Unset: ASFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, PORTAGE_RSYNC_EXTRA_OPTS
