[GRASSLIST:2810] NVIZ problems on Mac OSX

[Nick Cahill]

I am unable to get NVIZ to start successfully. Starting from the 
tcltk menu, I get an error message "<el=surface> is ambiguous". I 
assume this is an error in the tcltkgrass script, that NVIZ is 
looking for "elevation=surface" while the script is sending 
"el=surface". So I tried the simplest method I could: running nviz -x 
from the command line. This starts a bunch of windows, and then fails 
with errors:

I'm running GRASS 5 pre2 under Mac OSX 10.1, using precompiled 
binaries. I wondered whether it might be some oddness in my xwindows 
software or my version of TclTk -- but using both Tenon's XTools and 
XDarwin/XFree86, I get the same error. I then tried installing GRASS 
from OpenOSX's CD, but got the same error again. Any thoughts would 
be greatly appreciated.
