Julien, Thank you for the response. I'm not sure that ticket#520 is my problem. I don't think that the glut framework on 10.6.2 has been processed by bridge support.
I'm trying to teach myself openGL using the superbible and other web resources. To keep things simple I wanted to build the superbible examples in MacRuby - this should give me an easy to use platform for just trying to get my mind around the openGL paradigms. I agree with John Shea that GLUT is not the way to develop a real application. But for learning and trying things out its performance is just fine. My current thinking is to build a simple template project in MacRuby that uses a NSOpenGlView rather than GLUT. I would add boilerplate to provide animation, keyboard and mouse support (I'm thinking of using the Sojaster port of the Apple Cocoa OpenGL example as a basis). I'd be happy to share or work jointly on these efforts with anyone who has a similar need. It would be useful if there is a web site we could use to document such work and share code. Any ideas?
