The paths.py that is being imported is in the same directory as
postfix_to_mailman.py, i.e., /usr/lib/mailman/bin/paths.py

It's the value of prefix defined in /usr/lib/mailman/bin/paths.py, but
we know that's the same as used by bin/newlist.

We also know that Mailman and Postfix are working together. It's only
the web UI that's not working.

Web create is apparently creating lists because it either creates the
list or returns an error. If it succeeds, the list's
lists/LISTNAME/config.pck file is created somewhere.
