Whenever I try to build blender, it stops at ftgl, and I get:

checking GL/gl.h usability... no
checking GL/gl.h presence... no
checking for GL/gl.h... no
configure: error: GL/gl.h is needed
exit: Illegal number: please
exit: Illegal number: please

*** Error code 1

Stop in /usr/ports/graphics/ftgl.
*** Error code 1

Stop in /usr/ports/graphics/blender-devel

This is a headless system, so I don't have any GUIs installed.  I'm
just trying to install the minimum X needed for blender - so I may be
missing something.   The whole xorg 7.2 build process was clear as mud
for me.

Thanks for any help you can provide.
