#18 please backport this commit to install freeglut to auto, not bin

[Mithaldu]

With my experimental fork i ran into problems because it installed a different freeglut than the core OpenGL.pm does. Together with bulk88 i worked out a way to install freeglut in a generally nicer and more interoperable way. The changes can be seen in this commit here, and i think OpenGL would benefit from adopting them:
