nviz wouldn't run without it.

Ah, you were mixing the python.org python with the system's wxpython.   
The wx binary extensions in GRASS (the nviz and vdigit .so's) were  
linked to the system wxwidgets libraries, but then the GUI loaded your  
wxpython 2.8.8.1, thus some binary confusion.

Looks pretty much the same - it's trying to load a binary module, but  
it doesn't say what it is.

There are no system wx libraries now, which is good.


Just to test, try configuring without tcltk.  As Glynn pointed out,  
something is loading the X11 libraries, which are completely  
unnecessary within the Python GUI.  All those do is enable the tcltk  
nviz, and have nothing to do with the tcltk GUI anyways (if you want  
to keep that option open).  Even tho you configure with the aqua  
tcltk, maybe that's still getting some X11 into the mix.

with-x isn't causing me any problems, but if disabling tcltk doesn't  
help, try disabling X.

Of course, this may have nothing to do with nviz crashing, but it's  
worth a try.

Either Python should be fine.  I don't see a reason to stop using  
macpython if you want a more recent wxpython.

Reinstalling a recent wxpython for the system python would take  
compiling wxpython from scratch - the binary extension bits are linked  
to the macpython.  I've considered trying it out someday for kicks  
(and installing an updated numpy for the system python) - it should  
work.
