[Distutils] distribute_setup.py in package + setuptools 0.7.2 = package uninstallable

[Andreas Kloeckner]

Hi all,

I've shipped distribute_setup.py in a number of my packages. If a user's
install (be it virtualenv or otherwise) becomes "infected" with
setuptools 0.7.2, my packages appear to become uninstallable, with
errors like the log below.

Run the following script to reproduce:

8< ------------------------------------------------
#! /bin/sh

set -e
set -x

virtualenv --no-setuptools mypy
source mypy/bin/activate
curl -k https://bitbucket.org/pypa/setuptools/raw/0.7.2/ez_setup.py | python -
curl -k https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python -
pip install pudb==2013.1
