Hi, I've tried to install masked version of MesaLIb-3.5.ebuild v1.8 and after recompiling xscreensaver I get: $ xscreensaver-gl-helper xscreensaver-gl-helper: relocation error: /usr/lib/libGLU.so.1: undefined symbol: __gxx_personality_v0 $ ldd xscreensaver-gl-helper ldd: ./xscreensaver-gl-helper: No such file or directory $ ldd /usr/bin/xscreensaver-gl-helper libGL.so.1 => /usr/lib/libGL.so.1 (0x40029000) libGLU.so.1 => /usr/lib/libGLU.so.1 (0x4009d000) libpthread.so.0 => /lib/libpthread.so.0 (0x4013d000) libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x4018d000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40196000) libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x401ae000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40206000) libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x402e8000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x402fe000) libm.so.6 => /lib/libm.so.6 (0x4030e000) libc.so.6 => /lib/libc.so.6 (0x40330000) libdl.so.2 => /lib/libdl.so.2 (0x40460000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) mokrejs@vrapenec$ I've successfully downloaded MesaLib-5.0.tar.bz2 and compiled using: "make -f Makefile.X11 linux-x86" Don't rung configure! There're missing Makefile.in files! It seems, the tar.gz is fine (see the bugreport on sourceforge for MesaLib). Anyway, after installing manually the libraries from MesaLib-5.0/lib/* over those in /usr/lib I have no problems with unresolved symbols.

According to /usr/portage/profiles/package.mask: --------------------------------------------------------- # Only use the mesa and mesa-glu provided with x11-base/xfree, # as the external ones gives problems in most cases with DRI/DRM. # Nvidia users do not use it anyhow, and tdfx users report that # it works fine with the mesa included with xfree. If you do # unmask these, make sure that you know what you are doing, and # know that if anything breaks, then you get to keep the pieces. # # azarah (26 May 2002) >=media-libs/mesa-3.0 >=media-libs/mesa-glu-3.0 >=media-libs/sgi-oss-glu-1.0 >=media-libs/oss-opengl-glu-1.0
But for me the upgrade to Mesa 5.0 some of the OpenGL requiring screensavers started to work, finally! I don't have any troubles now, compared to the case before when the screensavers could not run(I remember some "SIGCHILD messages on the screen). I have ATI Mobility Radeon 7500-P7 using DRI/DRM, linux kernel-2.4.21-pre5 with UDMA/IDE patch.
