The ebuild was exiting with an error about not being able to find lablGL. I found /usr/lib/ocaml/lablGL/ and verified that the lablgl package was installed. Checking the build flags, it had "glut" turned off. I enabled it, rebuilt lablgl, and then lablgtk built fine. Reproducible: Always Steps to Reproduce: 1. emerge -u lablgtk 2. 3. Actual Results: I don't have the exact error message during the lablgtk configuration stage, as I have already fixed the problem. Expected Results: Given that the problem is with the glut USE flag not being applied when lablgl was built, it would be helpful to have the lablgtk ebuild check for that condition and refuse to start the build until lablgl was corrected. $ emerge --info Portage 2.1.6.13 (default/linux/x86/2008.0/desktop, gcc-4.2.4, glibc-2.10.1-r0, 2.6.30-gentoo-r4 i686) ================================================================= System uname: Linux-2.6.30-gentoo-r4-i686-Intel-R-_Core-TM-2_Quad_CPU_Q9450_@_2.66GHz-with-gentoo-2.0.1 Timestamp of tree: Sun, 27 Sep 2009 12:00:01 +0000 distcc 3.1 i686-pc-linux-gnu [disabled] ccache version 2.4 [enabled] app-shells/bash: 4.0_p33 dev-lang/python: 2.6.2-r2, 3.1.1-r1 dev-python/pycrypto: 2.0.1-r8 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: 2.1 sys-devel/autoconf: 2.13, 2.63-r1 sys-devel/automake: 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 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 -march=nocona -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /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 -march=nocona -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="buildpkg ccache collision-protect distlocks fixpackages parallel-fetch protect-owned sandbox sfperms strict unmerge-orphans" GENTOO_MIRRORS="http://distfiles.gentoo.org/ http://www.gtlib.cc.gatech.edu/pub/gentoo/" LDFLAGS="-Wl,-O1" LINGUAS="en" MAKEOPTS="-j5" 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="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X a52 aac acl acpi additions aiglx alsa ao apache2 audacious audiofile bash-completion bcmath berkdb bindist branding bzip2 bzlib cairo calendar cdinstall cdr cli cracklib crypt cups curl dbase dbus dbx dedicated dga divx doc dovecot-sasl dri dts dv dvd dvdr emboss encode expat fam fame fbcon ffmpeg fftw firefox flac flatfile font-server fontforge gd gecko-sdk gif gimpprint ginac glitz glut gnutls gpgme gpm gs gstreamer gtk hal hardenedphp hou iconv id3tag imagemagick imlib inifile isdnlog jack jpeg jpeg2k keyscrub latin1 lcms libnotify libsamplerate logrotate logwatch lzma mad mbox memlimit mikmod milter mime mmap mmx modplug modules mp3 mp4 mpeg mpm-prefork mudflap mysql ncurses no-suexec nocardbus nocd nodrm nomotif nowin nptl nptlonly nsplugin ofx ogg opengl pam pcntl pcre pda pdf perl php pie plotutils png posix ppds pppd python qt3support qt4 quicktime quotes readline realmedia reflection rtsp sasl sdl server session shared sharedmem simplexml skins smtp sndfile sockets sou spell spl sse sse2 ssl ssse3 startup-notification subtitles svg sysfs sysvipc tagwriting tcl tcpd threads thunar tidy tiff timidity tk truetype ups usb userlocales vhosts videos vim-syntax vorbis win32codecs wma wmp wv wxgtk1 wxwindows x264 x86 xine xml xorg xpm xprint xscreensaver xulrunner xv xvid zlib" ALSA_CARDS="ice1712" 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 cgi cgid 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" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en" USERLAND="GNU" VIDEO_CARDS="vga nvidia" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LANG, LC_ALL, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
its not due to the glut useflag, its fine here. it's just because you didnt run ocaml-rebuild.sh when upgrading ocaml that it can't find it.
