[GRASSLIST:3142] NVIZ and TK on Mac OS X

[Nick Cahill]

This is not specifically a GRASS question, but perhaps someone here can help.

I recently installed Grass 5 pre3 precompiled binaries on Mac OSX, 
and am getting an error when I start NVIZ:


  tsdptr 4729744 datakey 4729744
  start search mainPtr 0
  called create main window
  assigning interp 4700480
  tsd is 4729744 datakey 4729744
Application initialization failed: Can't find a usable tk.tcl in the 
following d
irectories:
     /System/Library/Tcl/tk8.3 /usr/local/grass5/etc/lib/tk8.3 
/usr/local/grass5/
lib/tk8.3 /usr/local/grass5/etc/library /usr/local/grass5/library 
/usr/local/gra
ss5/tk8.3/library /usr/local/tk8.3/library



This probably means that tk wasn't installed properly.

There is, however, an installation of tk8.3 at /usr/X11R6/lib. Where 
in Mac OSX do can I tell the system to look here for tk8.3? I don't 
see it in any of the GRASS startup scripts; I think it's somewhere in 
OSX.

Many thanks for any help you can offer,
