I don't see /usr/X11R6/include in there.

Check Platform.make, specifically OPENGL_X11 and XCFLAGS.

OPENGLINC doesn't actually get used in nviz/src/Makefile, although it
is used int the configure header checks; I'll fix that.

Ordinarily, XCFLAGS would add -I/usr/X11R6/include; however, that
might not happen if you have a symlink:

	/usr/include/X11 -> /usr/X11R6/include/X11
