Hi,

the MAXREPEAT error indicates that the system Python and the
Python of the virtualenv of CKAN do not have the same version
number.  Ubuntu 13.04 uses 2.7.4. I'm not quite sure how to fix
this in case of package install. With source install you could
just create a new virtualenv. It might be possible to simply
overwrite /usr/lib/ckan/default with a new virtualenv.
