No, it's not just ububtu.

They are following the recommended way. See "Creating system
packages", under

   http://peak.telecommunity.com/DevCenter/setuptools#what-your-users-should-know

In particular "--single-version-externally-managed".

The end result is that packages installed this way share a common
location, site-packages. I think this is extremely stupid.

If all you care about is installing one version of a distribution in a
system Python, this works fine, but it is a royal PITA for buildout.
