[Distutils] virtualenv & pypi-server

[Andrea Crotti]

Answering to myself, I was using the wrong functions for pkg_resources, and
in theory I should use find_distributions.
So I tried the following
- construct a very minimal egg with a foolproof module
- find and add to the working_set all the distributions found

for d in find_distributions('egg_directory'):
     working_set.add(d)

from foolproof import fool

And in fact in sys.path the foolproof egg is there, but then I can't still
import foolproof...
Is there anything else I need to do?

Here is what the egg look like..
