Here is the location of the native OGL (called AGL on Mac).

Which is a symlink to /System/Library/Frameworks/OpenGL.frameworks/
Headers/gl.h. Which is what you get when you configure with --with-
opengl=aqua.
Which spits out a bunch cpp errors in the Carbon includes, from the
AGL include. More than I can wrap my brain around at the moment,
but it looks like we need to work on this.
Learned a new trick today (probably standard stuff for the programming
gurus) - I added -E to the compile flags and found that an unexpected
macro was substituted for a buried Carbon struct:
typedef struct CMFixedXYZColor {
Fixed X;
Fixed Y;
Fixed Z;
} CMFixedXYZColor;
which came out as:
typedef struct CMFixedXYZColor {
Fixed 0;
Fixed 1;
Fixed 2;
} CMFixedXYZColor;
It appears X, Y and Z (all caps, that is) are defined in gstypes.h in
GRASS. I was able to fix the problem by moving the lines in nviz.h:
#include <grass/gsurf.h>
#include <grass/gstypes.h>
to *after* the GL includes.
