Reading this exchange, it sounds like provision of mipmaps is somehow
broken with OSX & OSG svn/trunk.  It would be worth looking at changes
to OpenSceneGraph/src/osg/Image.cpp, Texture.cpp and Texture2D.cpp.
It could be that a GL extension is broken under OSX, or something on
the OSG side that isn't working as intended, with the error only being
picked up under OSX.

I'm afraid I don't have an hunch as to what it might be though.

Robert.
