I had a newer version of ruamel.yaml installed, when I issued pip install -e . I got the pinned version of ruamel.yaml-0.10.23

$ sudo pip install -e .
...

References from our IRC conversation:
(08:55:05 AM) cory_fu: mbruzek: Hrm. It's pinned in requirements.txt: https://github.com/juju/charm-tools/blob/master/requirements.txt#L20 but not in setup.py: https://github.com/juju/charm-tools/blob/master/setup.py#L16

Please see #233. We need to update the pinned version as well, unfortunately.
