NVIZ seems to use its own version of wish that must be coded into a

wish somewhere. If that path could be redirected to whatever
GRASS_WISH is, then both GRASS and NVIZ could be in sync. The only
fly in this ointment would be if Togl must have the same version of
wish available (somewhere) that it was compiled against AND needs
other TclTk files in addition to wish.
That's probably some application API thing in tcltk. NVIZ just
needs the tcl and tk libraries that it was compiled with.
From what I can gather of the nviz source code, it makes its own wish
equivalent. So it will run with whatever it is compiled with
regardless of what is on the system--or in any $GISBASE folder--after
compilation. If this is so, an aqua version could be compiled against
8.5 aqua, with wish8.5 aqua included with the binary--and nothing else
needed. An x11 version could be compiled against 8.5 (or 8.4 I
suppose) x11 and wish 8.5 x11 included.
