Those missing module errors are not important. I get those errors every time I do ‘maya2egg’, it’s been that way ever since Maya added python support. Apparently, maya’s internal python distribution contains some extra modules. But when you run maya2egg, it tries to load panda’s version of python instead of maya’s version of python, and you get missing module errors. I’ll fix it someday, but it doesn’t affect the exporter anyway since the exporter doesn’t use python.
As for this error:
Maya binary file parse error: : (6) corrupted file structure
I’ve not seen that before. My hunch is that there’s some sort of version conflict here - maybe you’ve got two copies of maya installed? Maybe one is corrupted?
