pkgsrc was recently updated via anoncvs.
>Description:
When attempting to build freeglut from pkgsrc, the build fails.  The
error message says that it cannot find GL/gl.h or GL/glx.h.

It is able to find GL/glu.h, it seems.

The system has both /usr/X11R6/include/GL/gl{,x}.h from the system
install *and* /usr/pkg/include/GL/gl{,x}.h from pkgsrc's Mesa package.

The package *is* able to find the glu.h header.

Interestingly, this problem does not affect some systems.  A laptop
running -current (pre-2.0 userland, post-2.0 kernel) builds it
cleanly, for example.

./configure can be seen to fail to find working gl.h, glx.h or glu.h.
>How-To-Repeat:
On a "suitable system" attempt to build freeglut from pkgsrc.
>Fix:
I'm not sure why it's failing.  I have no workaround.
