Subject: nviz segfault on startup when creating display window

Platform: Mac OSX
grass obtained from: Trento Italy site
grass binary for platform: Compiled from Sources
GRASS Version: CVS 2006_06_24

Even with a simple quickstart: nviz -q, nviz is crashing with a segfault when it tries to create the 
output window.  From the OSX crashlog:

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_INVALID_ADDRESS (0x0001) at 0x5c637273

If I add an elevation raster from spearfish6 demo, it shows some status, then crashes with the same 
thread trace when trying to create the window.
