Warning: the following items did not execute (for py26-zopeinterface): org.macports.activate org.macports.build org.macports.destroot org.macports.install
Error: Status 1 encountered during processing.

I can confirm that using ​Distribute (Tarek's setuptools fork) to easy_install zope.interface with macports python 2.6.3 succeeds. Unless Tarek's changes make it back to py26-setuptools (which I suspect they won't), it would seem that upgrading to the latest python26 ought to somehow "swap out" py26-setuptools for py26-distribute without breaking the many packages which depend on py26-setuptools.

py26-setuptools was fixed in r58886, also see ​discussion on -dev thread about the future for distribute vs. setuptools.

Ah, this seems to effect py26-django too.

Is there a workaround for this?

That's not the problem this ticket was about at all. Just uninstall setuptools.
