 This particular package is needed by many opengl apps.
 Not all. But those who don't need it still like to build it as a
 reassurance that opengl actually works on their machine before building
 any other opengl project.


 Downgrading mountain lion and lion to an earlier working glfw and glfw-
 devel would be a solution: as most projects don't need the latest.
