Hi Miguel,
  Sorry for the delayed response, I've been out of town
for a couple of weeks, and I'm still feverishly working on
catching up on emails....

I think I know what the problem you are experiencing is...
You may have a libGL.so file out in /usr/X11R6/lib which
conflicts with the libGL.so supplied by NVidia, that gets
copied into /usr/lib/libGL*. If you rename this library to
/usr/X11R6/lib/ligGL.so.1.old or something, and then do an
ln -s /usr/lib/libGL.so /usr/X11R6/lib/libGL.so.1 things
should work fine. We have this same issue on our Linux
machines that have the NVidia drivers. (We just tried VMD
on a 750MHz Athlon, with a GeForce 2 GTS, WOW, quite fast!!)

Let us know if you have any other questions about this, or if
anyone has other suggestions for avoiding this particular quirk
with the NVidia drivers.

Thanks,
  John Stone
