Seconded. I have some games built with this I can't play now since some kind of OpenGL check fails. Haven't found a fix, yet.

Edit: In some cases, this may be due to a slightly too-old version of Mesa. Errors generated by the libs look like errors from the game. It's too ambiguous and not necessarily the game/engine's fault.

Was interested in checking this out but the inability to have it running on Linux unfortunately has kept me from digging in and investing...
