Yes, it looks like that did fix it.  There was another type of error which I
thought might have been resolved as well, but unfortunately not:

GL/xmesa.h: No such file or directory


As expected I find in vgui_accelerate_x11.h:

#if VGUI_MESA
#  include <GL/xmesa.h>
#endif

I think the pre-processor throws an error whether the conditional is met or
not, so I *could* just get rid of it and hope it's not important.  Of course,
I'd rather not.  In my include/GL directory I have glu.h and glut.h, with no
xmesa.h to be seen.  Do I need it, or is it a VXL problem?

Thank you.

Nick
