Often these are issues with improper setup.py configurations, by the authors of these packages. It's not uncommon for authors to forget to list their package dependencies in setup.py, for instance.

Forking these projects and fixing the setup.py is probably the best solution. If they're active projects and you'll want their updates, they're likely to accept your patch. If they're inactive, it doesn't really matter that you're using a fork anyway.
