[Rivet] Pythonpath

[Chris Pollard]

Hi Mohammadreza,

I see what looks like a mixture of python2.7 and python3 lib directories in
your PYTHONPATH. I don't know what the behavior of such a setup will be.

Rivet has not been tested (AFAIK) in a python3 environment: indeed some of
the updates are simple (such as "print" -> "print()"), but I think we have
to be careful about details of the cython configuration/compilation. It's
possible that you're compiling the cython bits with python2.7 libraries and
then trying to run with the default system python (which is 3.5)...

I really suggest only having python2.7 directories in your PYTHONPATH,
making a clean rivet installation, then seeing if it works as expected.

Chris
