nviz from the terminal is opening the TclTk NVIZ.  In the Python GUI  
it's the wxPython NVIZ.

So, you're saying that you did compile your own wxPython?  But then  
you rebuilt with the monolithic option?  Did you then distclean GRASS  
before recompiling it?

3 things to try:

- make sure you have /Library/Python/2.5/site-packages/wxredirect.pth,  
maybe your wxpython build didn't install this for some reason.  and  
make sure that you don't have any older wxpython junk in your site- 

- the system wxpython meets the minimum requirements.  Try deleting  
your wxpython and reconfiguring GRASS to use the system wxPython.

- try installing the latest wxPython binaries from the wxpython site,  
instead of compiling your own.

No need to set it then.
