No problem. Do note that there's an apparent issue with DRF 3.4 and
Django 1.10. It _should_ work, but it gives an odd warning. You can
probably ignore that particular combination given the age gap between
them.

Do be aware that those packages frequently carry backports from newer
versions and might be different to the version found in pip. Testing
with _actual_ system packages would be a far better indicator.

Also - I ran these tests last night and it took over an hour. That's a
bit long for anything non-automated, I think. Must find a better way.
