Kinda figured.  Had to ask.

Huh?  I'm using Tcl/Tk 8.4.13 framework (universal) I built on Mac  
10.4.7.  Seems to works - demos work except ones that the GMA  
graphics on my MacBook don't support.  There does seem to be a bit of  
an OpenGL problem on my MacBook - GRASS/NVIZ, where I need Togl, runs  
on a PPC Mac but crashes on my Intel Mac.  Maybe this bug you mention  
has something to do with it?

What's this patch for Tk you mention?

I'd still build from source - GRASS builds the Togl binary into it's  
NVIZ program.
