Comment # 3 on bug 1017360 from Stefan Dirsch

You're looking at the Mesa libs. With our RPMs NVIDIA's libGLs are installed in
parallel to Mesa below /usr/X11R6/lib64 and /usr/X11R6/lib (32bit). See also
/etc/ld.so.conf.d/nvidia-gfxG0*.conf.
This appear to work for a 32 bit glxinfo sample program.

# /tmp/usr/lib/mesa-demos/xdemos # ldd glxinfo 
        libGL.so.1 => /usr/X11R6/lib/libGL.so.1 (0xf76f9000)
        libnvidia-tls.so.304.134 => /usr/lib/tls/libnvidia-tls.so.304.134
(0xf7410000)
        libnvidia-glcore.so.304.134 => /usr/lib/libnvidia-glcore.so.304.134
(0xf5709000)
        [...]

Where can I download ANSYS fluent and/or gambit for testing? I guess they are
dlopening /usr/lib/libGL.so.1 directly (getting the Mesa one) or something
alike. I considere this a bug in the application. ;-)
