I don't like these parasite libraries here. Did they came from
uncommenting the lines? How the line #84 hack worked? I was hoping that
that would solve the problem.

This is an easy one. Whether are you using very old f2py (you'll need the
latest) or there are old object or library files around. In the latter
case just removed them and rebuild. I recommend 'rm -rf build'.
