Comment 44 for bug 1073730

So I just spent an hour going through possible problems w/ user running 13.04 who was failing to launch the engine.

Finally figured out the package for 13.04 was built against freeglut3 (video recording) but did not include that as a package dependency.

That is, game will not function on any Ubuntu 13.04 system where the user does not have freeglut3 already installed.
