How can a module with setup.py installed using Cython?

First I've no experience with python. I just want to install a module in
blender which comes with a setup.py. It seems that I need Cython to
install that. I added Cython to PYTHONPATH and the bin folder to the PATH.
This error is shown:
python setup.py install
running install
running build
running build_ext
Traceback (most recent call last):

Any ideas, what should I try?
