From Ryan Pavlik, "I have successfully compiled OpenSceneGraph trunk using the Clang compiler (using a recent trunk build of llvm and clang, haven't tested an older release).

It fixes an issue with two-phase name lookup - there's more information here http://blog.llvm.org/2009/12/dreaded-two-phase-name-lookup.html
