clone https://github.com/menghan/setuptools-test-prj and run python setup.py install in a virtualenv, setuptools didnot install all required packages using link from dependency_links.

https://gist.github.com/menghan/8178588 is my local output. Setuptools install sh by dependency_links' link, but pep8 not.
