As I mentionaed a while back, for the nviz library to operate cleanly  
with wxpython, which is "Aqua", or AGL-based, you should configure  
OpenGL for Aqua, not X11.  This means you should also disable X11 and  
TclTk features, or you will get some header confusion for OpenGL.   
Something like:

--without-tcltk --without-x --without-motif --without-glw --with- 
opengl=aqua

But, when I do this I get:

gcc -I/Users/Shared/src/GRASS/svn/trunk/dist.i386-apple-darwin9.3.0/ 
include  -Os    -fno-common   -DPACKAGE=\""grasslibs"\" -I/Library/

It seems to be some AGL programming issue.
