Here's my file layout:

__init__ and test_enum are both smart enough to pull in the correct code when imported. The issue I am having is this:

distutils is trying to load the py3 versions, which of course fails on a py2 install. The package installs successfully anyway, but if I were a user I would be wondering if the install was trustworthy.
It seems to me that I need to either have distutils only install the version appropriate files, or to not try to scan the version inappropriate files, but at this point I do not know how to do either.
Any pointers would be greatly appreciated.
That's odd. I work on a package that ships Python 2 and Python 3 versions of some modules and I have never seen this problem before. Perhaps you could post your setup.py?
If I recall this is because it's trying to compile byte code.
That's correct. And you'll note that despite the scary-looking syntax errors from byte-compilation, the install actually succeeded. Carl
