+;;; Some packages (notably, certbot and python-acme) rely on this newer version
+;;; of python-mock. However, a large number of packages fail to build with
+;;; mock@2, so we add a new variable for now. Also, there may be a dependency
+;;; cycle between mock and six, so we avoid creating python2-mock@2 for now.
