You would probably be better off using the find_links option in your 
setup(), to indicate additional URLs where packages can be 
found.  e.g. find_links=['http://pypi.example.com/somepackage', 
'http://pypi.example.com/otherpackage'].  This will tell easy_install 
(or other packaging tools) to check these pages in addition to the 
standard package-index pages, when seeking out your dependencies.
