Commit 13cf059d authored by jim's avatar jim

- If a distribution defines namespace packages but fails to declare

  setuptools as one of its dependencies, we now treat setuptools as an 
  implicit dependency.  We generate a warning if the distribution
  is a develop egg.

- Remove old develop egg links. This requires storing the old link
  paths in .installed.cfg.

Bugs Fixed
----------
- Egg links weren't removed when corresponding entries were removed
from develop sections.

Often, a package depends on setuptools soley by virtue of using
namespace packages. In this situation, package authors often forget to
declare setuptools as a dependency. This is a mistake, but,
unfortunately, a common one that we need to work around. If an egg
uses namespace packages and does not include setuptools as a depenency,
we willll still include setuptools in the working set. If we see this for
a devlop egg, we will also generate a warning.
