That depends on which version you're using. It works on 10.0, at least on my computer, but if you have XGL running on 10.1 I believe it breaks it.
If that's not the problem, make sure you have OpenMotif and the proper graphics drivers installed, failing that run it from a terminal (should just be realsoft3d) and see if it says anything there, I can't remember off the top of my head if there's a specific debug or verbose command and I'm not at my desk so I might have more to add.
