[Distutils] Setuptools: build_requires?

[Jeroen Ruigrok van der Werven]

So I am curious, why doesn't setuptools provide a build_requires directive
similar to install_requires, but for python setup.py build?

Right now a particular Python module will fail if you import said
dependency somewhere in your code.

Centralizing such a dependency in setup.py seems, to me, very logical. So
what gives?
