Jenkins/tox fails to generate docs

[Deepti Ramakrishna]

Hi,

When we run "tox" in fresh clone of glance-specs repo, it fails with the below error (full log can be found here: http://paste.openstack.org/show/475234/):

Failed to build Pillow

This causes Jenkins also to fail on any submission. I noticed this issue when I tried to upload a new spec (https://review.openstack.org/#/c/230679/) to the Glance-specs folder and it failed.

Seems to be the same problem in devstack doc generation: http://logs.openstack.org/93/223093/4/check/gate-devstack-publish-docs/4dff8ac/console.html
