easy_install-2.3 got me a -dev egg (4205?) that did not have the declarative extension

what's "easy_install-2.3" ? I just did an upgrade to the latest, the version is "0.6c8". Oh, you mean on Py2.3. Well, running 2.5, I get:

There's nothing 2.3/2.4/2.5 specific in our setup.py file, and the version on cheeseshop is a source file (no version-specific build) so your issue likely lies with setuptools.
