[Zope] PoPy

hello everybody, I am new with Zope and I don't know Python. I want to use Zope with PostgreSQL. I have installed PoPy-1.2.1 and compiled the module PoPymodule.so. I have also installed ZPoPyDA.0.7 in /lib/python/Products/ZPoPyDA/. My problem is I don't know if I have to compile the Phyton files in ZPoPyDA ? I have tried, and some errors appeared : when compiling __init__.py : ImportError: No module named Globals when compiling PoPy_db.py : The PoPy module is old: Update your version of PoPy So, I tried to install PoPy-1.3.6, but I failed! Is there someone who could help me ??? :-(
