Allow ansible to install on darwin platforms

I am using this package on my Yosemite install of OS X and it works great. It also pretty closely follows the Homebrew recipe that most OS X users use, so I think we can open it up to other OS X users.

Removed all versions of geant4 except for the latest one.
