I am running into a issue that go introduced today from pytests where they are broken for python 2.7 (https://github.com/pytest-dev/pytest/issues/4770) from my understanding their isn't a way to pin the dependency (more-iteratools) that is causing the problem. Looks like some of the other packages are configurable for pytests in (https://github.com/pantsbuild/pants/blob/master/src/python/pants/backend/python/subsystems/pytest.py) anyone else running into this issues? Can open up a github issue if that is better
