[Zope] Zope error while connecting to Postgresql from APE

[Subramanian S]

Hi,
  I have installed Zope and APE. I have added a Postgresql mount point in 
zope.conf.
Now when I try to connect to 'Zope Management Interface' and a ZODB mount 
point for postgresql, the error I get is :-
Error Type: ImportError
Error Value: /usr/lib/python2.3/site-packages/psycopgmodule.so: undefined 
symbol: PQresultErrorField


What do I do?

Regards,
Subramanian S
