[Zope] Which Postgres is best for Zope/Plone on OS X, package or fink install?

Hello, I am using my OS-X iBook as a devlopment platform and I have recently installed the combination Plone/Zope install.. I'm hoping to use this install with Postgres, but there are several installation options.. There is a OS-X 'package' (which comes off the Postgres official site) and.. There is a Fink package (which is basically a OSX version of a Debian package) or.. I could insall Posgres from source.. The primary reason for installing Postgres is to use it with Zope, so ease of interfacing the two is my main concern, since I've had problems getting Psycopg to do this in the past.. Does anyone have any suggestions? -Chris
