"prevent setuptools from resolving the dependencies" actually means "Hey setutools, just install Foo into site-packages, but don't bother about its dependencies".

Each installed package has a 'requires.txt' file that lists the dependencies of that package. pip presumably uses this file. 

$ cat ~/.local/lib/python2.6/site-packages/pylint-0.19.0-py2.6.egg-info/requires.txt 
logilab-common
logilab-astng >= 0.19.2s
