I'm eager to merge this but can't get the tests to run. I always run `make check` on charm-tools since that includes the integration tests as well. According to the Makefile that should still work, but I get:

tvansteenburgh@trusty-vm:/tmp/charm-tools> make clean
find . -name '*.py[co]' -delete
find . -type f -name '*~' -delete
find . -name '*.bak' -delete
rm -rf bin include lib local man dependencies
tvansteenburgh@trusty-vm:/tmp/charm-tools> make check

Note in this instance I had not yet run `pip wheel -w dependencies/python -r requirements.txt`, but even after doing so I get the same result.
