Trying to install DBD::Pg

I got a MacBook two days ago.
My wife has had one for a year and it looked like a good thing.

I've been doing all this perl stuff on Debian & Solaris for almost a  
decade.
But I'm not familiar with how it's supposed to be done under Mac, so  
I'm rather stuck.

Objective: install postgresql client software and drivers necessary  
to access remote postgresql databases.  A local database is not  
required since sqllite3 is present and should suffice for development  
work.  My expectation is that I can log in to a remote database using  
psql and perls DBI or DBD::Pg modules.

I have installed the following today:
Xcode (gcc & make)
DBI
Bundle::CPAN

from CPAN.  This also included YAML.

and Fink & MacPorts -- but nothing else from these.

I also have found that pgsql is already on the notebook and works  
correctly.
I also found the pg_config file in:
/System/Library/CoreServices/RemoteManagement/rmdb.bundle/bin/pg_config
But when I put this in for my path to pg_config I get the following  
(YAML?) related error immediately afterwards.:

Checking if your kit is complete...
Looks good
Note (probably harmless): No library found for -lpq

Writing Makefile for DBD::Pg
YAML Warning: Parsing a 1.2 document with a 1.0 parser

         YAML::Loader::_parse('YAML::Loader=HASH(0x4f939e0)') called  
at /Library/Perl/5.8.6/YAML/Loader.pm line 22

And it spews a few dozen more lines that I truncated.
I'm not sure what I need to do at this point.  There isn't anything  
here that says the problem is the postgresql libraries or anything  
like that.  Rather a YAML issue.

The funny thing is the claim that the Parser is a 1.0 parser when *I*  
think it's the most up to date available (which is version 0.67) so  
I'm not in the right point of reference on the version.

I'm really hoping I can get this working soon.
It's kind of killing my progress and whole point of getting a MacBook.

Help?
