Why has fedpkg suddenly grown a dependency on MySQL-python?

Are you able to upgrade to a later Fedora?  I think you're seeing this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=754538

which is a confluence of the update policy and conflicting use cases wanting
a bug to either be fixed or not.  In Fedora > 14, this shouldn't be an
issue.

Note that for your use case, this dep chain might also be breakable in
python-sqlobject.  For python-sqlalchemy we decide that we only explicitly
rely on sqlite (which is provided by python itself these days).  We treat
MySQL and postgres backends as optional deps that users or applications must
explicitly install if they want to use them.
