install things into %{_datadir}/israwhidebroken rather than directly into %{_datadir}::
 /usr/share/israwhidebroken/israwhidebroken
 /usr/share/israwhidebroken/israwhidebroken-0.1-py2.6.egg-info

The israwhidebroken.cfg changes are only needed for debugging.  In production, do not make those changes.
