Import error in python 2.7

[votti]

When importing polo in python 2.7 I get the following error after installing polo with pip:

/home/votti/.virtualenvs/python2_env/local/lib/python2.7/site-packages/polo/__init__.py

 in <module>()
----> 1 from polo.polo import optimal_leaf_ordering

ImportError: No module named polo

This appears to be solved with feba77db91d21504dcd2fca887f2cbafa777b36c. Installing polo from this repo rather than pip works successfully in python 2.7.
