Description of problem:
setuptools 0.6c6 has a problem with multiple versions of an egg that are fixed
in the 0.6c7 release.

Version-Release number of selected component (if applicable):
0.6c6 exhibits the bug.  0.6c7 does not.

How reproducible:
Everytime

Steps to Reproduce:
1. Install parallel installable python-cherrypy2-2.2.1 and python-cherrypy-3.0.2
packages that follow the new Python Egg Guidelines.
2. python
3. >>> __requires__='CherryPy>=2.0,<3.0'
4. >>> import pkg_resources
5. >>> import cherrypy
6. >>> print cherrypy.__version__
  
Actual results:
3.0.2

Expected results:
2.2.1

Additional info:
I would like to see this package upgraded in rawhide to address this as the new
Egg Guidelines are going to start exercising that portion of the code.

Alternatively, we can use this patch from upstream that fixes only this problem.
