Comment 8 for bug 563060

Python packages that have 'setuptools' in they install_requires have this dependency translated to python-pkg-resources by van.pydeb. It works most of the time, except when pkg_resources.require is used (like paster from python-pastescript does). This was solved in Bug #572609.

So in the end the behaviour of van.pydeb that "fixed" http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543551 is incorrect.
