I haven't tried compiling GRASS in a while, busy with other stuff.  I  
thought vdigit compiled - the makefile has the correct compile flags  
to handle libgdi.

Yes, nviz has the problem where you need to disable render.c (and lose  
nviz_cmd).  The OpenGL programming is too deep for me.


There is a separate issue (not critical) that I'd like to see fixed  
someday - Python linking.  Currently any binary code that uses python  
(vdigit, nviz) links the python binary.  At least on OSX, this is not  
the proper way to do it.  It's more like the dynamic lookup flags used  
in vdigit to handle libgdi, but it requires knowing the full path to  
the python binary, which is tricky in OSX.

It was discussed a while back, but Glynn was reluctant to put Python  
path-detecting code in configure.

The main benefit of all this is that whichever python binary was used  
to compile GRASS, *any* compatible python binary can be used to run  
GRASS.  ie, compile using the system python 2.5.1 on Leopard, but run  
using the python.org Python 2.5.2.  I'm seeing a lot more people  
preferring the up-to-date python over the system python, though I  
personally prefer to stick with the system python.
