[Zope] PoPy.2.0.1 Needs Postgresql?

The error I get is listed below. I'm trying to install the stuff that will allow for me to work with Postgresql, and I'm following the HOWTO -- actually, I'm not. I can't believe that I have to *un*install Postgresql to get PoPy to work. That doesn't make sense. Besides, I don't work with source much anyway, I've got Debian ;-) Anyway, I did the ./configure, and this is the error I get. Anyone know what I can change to get it to work? checking for PQconnectStart in -lpq... no configure: error: can't build without PostgreSQL libraries Thanks! Russell
