I'm not sure if that's an issue which can be fixed in a new QT-Version, but I would really appreciate if someone could have a look into this:
I'm not sure about the current state, but I know the maintainer of OpenGL stuff in Qt 5 is working on a Mac, so I guess it should be fixed in Qt 5.2.
You can raise the issue on IRC, development Mailing List, or ping ZapB on this forum.
Have you tried building your own version of Qt from source instead of using the provided binaries?
This might fix your issues by using the proper headers on your box.
