[GRASSLIST:4390] NVIZ ok on Debian woody

[Michele]

Thaks very much for your help, now NVIZ works.

To prevent loss of time to other people I would like
to point the packages to use,

This packages are ok with Xserver without GLX extension:

"mesag3", "mesag-dev", this are true names of Debian packages.

and do not use a site file to test NVIZ (maybe there is a problem in 
NVIZ with site files?).

Bye, Michele.
