Would appreciate any pointers on how to get the dependencies installed on Mac OS X.

Answer 1

It seems to be some problem with setuptools -- the dependencies are compiled succesfully but not installed. FWIW it works for me (OSX 10.5.6, MacPython 2.5).

I would try reinstalling setuptools, and if that fails downloading and "python setup.py install"ing cogen and py-kqueue manually.

Answer 2

Try downloading 'pip' (http://pypi.python.org/pypi/pip) and use that instead of easy_install. It just worked for me.
