No big deal.

Nothing.  The fact that the renderer string is "Mesa DRI VoodooBanshee 20010104"
says that all is well.  Depending on how glxinfo was compiled, different
libraries may be reported.  All that matters is that libGL is resolved
to the DRI libGL and not the Mesa libGL.

You'll get libGLU.so and libglut.so.  It's up to you to install them
in /usr/lib/ or /usr/local/lib/ as you choose.

Sounds like all you need to do is grab libGLU.so and libglut.so
from the DRI Resources page.
