Yes, you have completed only half of the installation process.
You also have to compile and install PoPy.

PoPy is a C-extension module for python that provides the actual
adapter that ZPoPyDA uses to talk to PostgreSQL.  

Note:  You did not say how you installed your Zope or your python.  
It makes a difference.
The PoPymodule.so must be placed somewhere in the PYTHON_PATH used
by your zope.  Source installed zope's generally do not modify
the system PYTHONPATH, and it would usually go in
/usr/local/lib/python2.1/site-packages, or something like that.

Binary installed Zope's generally DO modify the system PYTHON_PATH.
(But I forget exactly how; I think there is a python directory in
your $ZOPEHOME).

As to pyschopg being actively revised... Well, so is PoPy.  The least
release of PoPy is what, 3 weeks old?
