I'd only mention that Storm has a C extension/non C extension flag as well, and only offers one source distribution on Pypi. You have to modify a variable directly within setup.py. Our setup.py features the same capability (its just our C extension is off by default for 0.6 since it was just written, which is the same case for when Storm first introduced its C extension).
