Quoting Python 2.6 Ubuntu changelog:
"* For locally installed packages, create a directory
/usr/local/lib/python2.6/dist-packages. This is the default for
installations done with distutils and setuptools. Third party stuff
packaged within the distribution goes to /usr/lib/python2.6/dist-packages.
There is no /usr/lib/python2.6/site-packages in the file system and
on sys.path. No package within the distribution must not install
anything in this location.

I guess what happens is:
* virtualenv creates only $ENV/usr/lib/python2.6/site-packages because it doesn't check where Python distribution expects local packages to go.
* then virtualenv invokes setuptools which looks for $ENV/usr/local/lib/python2.6/dist-packages/ and bails out.

Correct me if I'm wrong, this is what i've deducted after short work with virtualenv-1.3.3.

virtualenv still works with python 2.5 because dist-packages and whole split into /usr/local/ vs. /usr/ was made in Python 2.6.. Well, according to changelogs.
