Comment(by cmbarton):

 The fact that this runs on the Mac OS that is 2 generations old, is
 encouraging. But the fact that it doesn't run on the 2 most recent
 versions of the Mac OS is a big problem. Hopefully this will turn out to
 be a Mac compiling issue that William and I can work out. But it still may
 be something in the wxNVIZ code that is only showing up now in current
 versions of the OS. So releasing a stable version (i.e., that can no
 longer be altered) with an important part of GRASS non-functional is
 something that I don't think we should do. So we need to at least figure
 out what is wrong. Anyway, I just updated dependencies (frameworks) and
 tested William's new build of GRASS 6.4.3. In this case, 3D does not work
 at all, but maybe the errors will be helpful in trouble shooting the
 problem.

 Message on starting GRASS:

 {{{

 3D view mode:
 dlopen(/Applications/GRASS-6.4.app/Contents/MacOS/lib/libgrass_ogsf.6.4.3svn.dylib,

   Referenced from:

   Reason: image not found

 }}}

 Starting 3D mode failed after:

 1) opening JR_2008_ALL_dem in the layer manger
 2) opening jr_7408MR_2m_t70 in the layer manager
 3) setting region to match jr_7408MR_2m_t70 using g.region
 4) displaying layers (JR_2008_ALL_dem only shows)
 5) switching to 3D mode in the display

 Here is the error:
