[issue8927] Handle version incompatibilities in dependencies

[Sridhar Ratnakumar]

Dave, but aptitude contains a local index of all dependency information. Whereas, PyPI's infrastructure and pip/easy_install/p7g.install do not rely on one. Therefore, I think when Tarek said "Trying to do something smarter is very very hard and will probably fail." he is referring to doing such dependency resolution *with* the constraint of lack of such local metadata index.
