where "python" itself moved on to 2.7 from Fedora 14 onwards.

Not sure why it was built for FC13:
http://koji.fedoraproject.org/koji/buildinfo?buildID=203123

python-sphinx10 has a "dead.package"; see e.g.:
http://pkgs.fedoraproject.org/gitweb/?p=python-sphinx10.git;a=tree;h=refs/heads/f15/master;hb=refs/heads/f15/master

so presumably this is a false positive.

I don't seem to be able to set a priority on this, but it's only a minor annoyance.
