What's the equivalent of
python setup.py build_ext --inplace


brief google search (I didn't follow up on those)

https://github.com/pypa/pip/issues/1887

Given that I rely completely on binary distributions for numpy and scipy, I
won't be affected.

(I'm still allergic to pip and will switch only several years after
everybody else.)
