Error when using wrong version of pip

[pierrei]

I was attempting to create a virtual env for the new logservice (located in its own github repo created by Endre) using ./setup.sh in the root of the project. It was on my local MacBook Pro NOT having activated any other virtualenv (using system python that is).

After a while I got this:

   Running setup.py egg_info for package mock
