I am running the OS X EPD distribution, which uses Enstaller (built on setuptools). Could this have something to do with it?
Sorry, but yes, this is exactly the problem. EPD comes with Enstaller instead of setuptools, and thus there is no installed project called 'setuptools', so pkg_resources.require('setuptools') isn't going to find anything.
As a quick fix, you could re-write the code you have as pkg_resources.require('enstaller') and be on your way.
I think a better, and longer term, fix is for us to patch the 'require' method in Enstaller's version of pkg_resources so that it catches a request for setuptools and maps it to Enstaller. This is probably safe because you can't have both Enstaller and setuptools installed without getting errors, plus Enstaller includes a patched version of setuptools.
