So it appears to me that none of these techniques are both modular/

are we to do?
We could be modular if there was a way to specify pre-setup.py
dependencies. Unfortunately, there isn't such a thing at the moment,
short of calling setup() twice, and forcing the first call to have no
script arguments, just a setup_requires argument.
Of course, that'd only work if setuptools were present, and it would
also force an immediate download of the build dependencies in
question. Something like:
try:
from setuptools import Distribution
except ImportError:
pass
else:
Distribution(dict(setup_requires=[...]))
If you want to get fancy, you could replace the "pass" with printing
some user-readable instructions after attempting to see if your
build-time dependencies are already present.
