Adding to zolointo's answer, the cython installation worked fine after following your instructions. I'm installing Kivy with Python 3.4.1 on Windows 7. Kivy requires Cython. After downloading Cython and running the installation scripts I received the following error:

Cython compilation Problem "error: Unable to find vcvarsall.bat"

Researching that error took me down the path of installing MinGW. If The MinGW installer overwhelms you with optional packages, doc, lic, bin and dlls to install. I installed the ones you mentioned above.

if you run:

python setup.py build_ext --inplace --compiler=mingw32'

you'll get a list of errors ending in:

TypeError: unorderable types: NoneType() >= str()

To fix that I followed zolointo's instructions adding MinGW to the PATH and creating a distutils.cfg file. At that point you can run the setup.py for Cython and everything works!
