I'm using the standard windows binary installer for python 2.7, which (to the best of my knowledge) was compiled with VS 2008, and uses the msvcr90.dll, which I have (I know that I have them due to having to wrangle py2exe packing for the application). Again, my application works just fine, since python 2.7 uses msvcr90.dll. I don't actually need the msvcr71.dll that the alert box is talking about. I'm trying to figure out why importing OpenGL.GL is telling me that I need that file, when I actually don't need it (presenting end users with a spurious error message on startup isn't acceptable, especially for the support guys ;).
