[Bug 1183634] [NEW] cheetah pkg does not depend on markdown, but egg requires.txt does

[Launchpad Bug Tracker]

cheetah 2.4.4-3ubuntu1 dropped dependency on python-markdown to avoid a
component mismatch (markdown is in universe).  Apparently the package
functions fine without it, however, cheetah's requires.txt still lists
it as a dependency:

$ cat Cheetah.egg-info/requires.txt 
Markdown >= 2.0.1

This causes any package that depends on cheetah and uses pkg_resources
to manage its dependencies to fail.  Caught with nova:

# nova-manage 
Traceback (most recent call last):
  File "/usr/bin/nova-manage", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2707, in <module>
    working_set.require(__requires__)
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 686, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 584, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: Markdown>=2.0.1
