As discussed in https://bugzilla.redhat.com/show_bug.cgi?id=601725 there is a namespace conflict between the python-mock module (http://pypi.python.org/pypi/mock) and the module provided by Fedora's mock.

It seems there is an agreement to rename Fedora's mock namespace to mockbuild, so as soon as this change lands in mock revisor will need to be updated.

The proposed patch adds compatibility with both old and new namespaces
