glfw fails to build on lion and mountain lion, x86_64 mac. glfw-devel also fails to build.

The error on mountain lion is:

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.
