That's a known 'feature' in setuptools. When it sees a .pyx file, it checks
for Pyrex being installed instead of Cython, and if that's not the case, it
changes the .pyx into .c, which obviously breaks the build.
What you can do is to provide a fake Pyrex in your sources, like this:
http://codespeak.net/svn/lxml/trunk/fake_pyrex/
and include it in your Python path as at the top of this setup.py file:
