Installation of Postgres + PHP

Hi, I followed the instructions at
http://users1.50megs.com/tomcat/postgresql-tutorial/
which describe in very simple terms how to install Postgres and Apache with
PHP support.

It didn't work! The main thing is that PHP didn't have the postgres support
listed in the additional support info.

Does anyone know of similar step by step tutorials for the computer
challenged like myself?
Thanks!
