Sorry about rst2pdf 0.10, have some 0.10.1 instead.
So, rst2pdf 0.10 was not ok. The setup.py that worked on 0.9 simply didn't work for the new version.
Good thing is, Christoph actually undestands setuptools, so he could fix it and deliver a neat 0.10.1 for your PDF-generating pleasure.
Post 0.10.1, I have already fixed one bug, Issue 117.
