It looks like it's failing due to a bare relative import inside the python stdlib tokenize library, so I'm not sure if there's anything gopy can do about.

But I did want to at least get this up in an issue so some other poor soul like me can stumble across it and save some hair-pulling by renaming one of their modules.
