  The only version available via PyPi is 2011.3.1 - which is far too old
  to run on Essex - and the most recent version of Glance is not
  compatible with Essex - Nova Essex has a bug where it just requires a
  version of glance >= 2011.3.1 - but that ends up fetching the latest
  version that is targeted to Folsom.

  I was hoping that I could at least install the Essex version of
  Glance, which I believe is 2012.1.2 - but it seems that you guys nuked
  that one.

  (.venv)scolli001c@HQSML-1081304 ~/git/comcast/nova ±comcast/essex⚡ »
  pip install -r tools/pip-requires

  No distributions matching the version for glance==2012.1.2 (from -r tools/pip-requires (line 22))
