This is a complete guess, but is it possible that your issue is the same
issue as this?

https://github.com/pypa/virtualenv/issues/278

I notice that this path has a space in the name:
/var/lib/jenkins/workspace/Service
Templates/TOXENV/py27/scripts

Incidentally, I recently experienced the same error and stack trace, but in
a slightly different context:

https://github.com/pypa/virtualenv/issues/281

In both cases, it looks like the easy_install is not getting installed when
virtualenv installs distribute.
