Ok, I spent a few hours on this and can re-produce it easily on a debian
unstable chroot using the gutsy package.

Though I'm still totally confused, apparently apt thinks the package on
the server is different from the package that's been installed. It
believes this even though the md5sum and version of the file in the
"Packages" index and the filesystem file match exactly. The only
difference I could detect is that the Packages file is lying about the
maintainer field (seems PPAs do some munging of package metadata).

I believe this to be a bug of either the PPA archive maintenance
software or apt or the Ubuntu PPA builders or a combination of all of
them. Perhaps filing a bug against launchpads PPAs might be the best
idea for further action (feel free to CC me).

You can see the difference between the way apt treats zope3 and
python-zope.ucol:

root at unstable /root # apt-cache policy python-zope.ucol
python-zope.ucol:
  Installed: 1.0.2-r77900-2ubuntu2
  Candidate: 1.0.2-r77900-2ubuntu2
  Version table:

root at unstable /root # apt-cache policy zope3
zope3:
  Installed: 3.4.0~b2-1ubuntu2
