My use case at the moment is trying to build conda packages from other
peoples' Python packages - if they use setup_requires, etc, then I'm stuck
with it.

Also -- for my packages, I want them to be easy to build and deploy by
others that aren't using conda -- so I need a way to do that - which would
be setuptools' features.

So I'd like the features of the "official" python packaging tools to
cleanly separated and not assume that if you're using setuptools you are
also using pip, etc....


Also, for the whole distutils-sig, I don't understand all the fuss around

None of those are cross platform, though. That still may be the way to go.

I like to keep in mind that with all this pain, in fact, even raw distutils
is freaking awesome at making the easy stuff easy.

( pip and pypi too...)

i.e. I can write a simple C extnaion (or Cyton, even), and a very simple
boilerplate setup.py will let it build and install on all major platfroms
out of the box. Then I put it up on PyPi and anyone can do a "pip install
my_package" and away they go.
