Yes, I did with my last attempts (in earlier attempts I did pull earlier
versions from github but only before I realized I had to upgrade cython
altogether). So that's probably it; sorry, I had no understanding of the
workings of pip.
I'll retry with cython stable and numpy from source, and only post again if
I find something surprising in order to reduce further noise.
