pjnius build fails on Arch Linux when requiring netifaces

[rdoursenaud]

Looks like it's calling a ptyhon3 version of something instead of the python2 one.
Tried fiddling with environment (make python, cython, cythonize and nosetests call python2 versions using the /usr/local/bin trick) for a while to no avail.
The very same project builds fine in the kivy-provided (extremely slow) VM.
What am I missing?

Here's the relevant log part. Let me know if you need more.
