How does NVIZ fail? Is there an error message? We could try to fix it.

Installing in a directory with spaces is never a good idea. There are 
various little things here and there that will break, although the 
situation is better than it used to be. In particular, I think shell 
scripts invoked with the batch file wrapper to GRASS_SH (normally set to 
the Msys shell) will fail because of a documented bug in the Windows 
_spawnlp() function which is used in g.parser. I used to have a fix for 
this (I think it just involved some extra quoting of the script name) in 
my local source tree but I never committed it because I wasn't very sure 
if it was the best solution, and I think I have lost it now in the move 
from CVS to SVN.
