8 years ago Based on your error messages, it looks like you're missing the Python header files needed to build C extension modules. As you noted, the C version is not required though. The easiest way to get up and running is probably to just clone the git repository and comment out the extension module in the setup.py file. It'll then install the pure Python and ctypes-based implementation. The ctypes version is almost as fast as the C extension so it'll probably be good enough.
Btw, what's your project?
