  pkg_resources.require() throws a DistributionNotFound exception if
  python-setuptools is not installed

Status in “zope.interface” package in Debian:
  Fix Released

Bug description:
  Many packages now depend only on python-pkg-resources and not python-
  setuptools, so the latter may be removed if it was automatically
  installed. However, in that case the whole mechanism stops working:

  $ python
  >>> import pkg_resources
  >>> pkg_resources.require('zope.interface')
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "pkg_resources.py", line 648, in require
      needed = self.resolve(parse_requirements(requirements))
    File "pkg_resources.py", line 546, in resolve
      raise DistributionNotFound(req)
  pkg_resources.DistributionNotFound: distribute

  This happens because zope.interface has setuptools in it's *.egg-
  info/requires.txt, like many other packages, but in reality only needs
  pkg_resources, and that's what is installed. Distribute is not needed
  at all, so it is a bug that this breaks in such a way.
