I get this error: python2.7 setup.py build Development mode: Compiling Cython modules from .pyx sources.

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
