Cannot Build Seesaw

[Candunc]

I cannot install via 'pip install seesaw', nor downloading the source from github and running 'pip install -r requirements.txt'. Both result in the following errors:

RuntimeError: maximum recursion depth exceeded ... Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-rNEiT_/seesaw

or

RuntimeError: maximum recursion depth exceeded ... Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-fIgLud/Tornado

This is on Ubuntu Server 14.10 64bit, with all dependencies installed.
