Apache module not installing with PHP

I used a stackscript to get a LEMP server setup, and now I'm trying to install Apache to run a proxy pass setup. PHP-FPM was installed with the stack script.

I've followed the instructions in this guide

http://library.linode.com/lamp-guides/debian-6-squeeze

but there is no /etc/php5/apache2/php.ini file and when I run apachectl -M it does not show the php module as loaded.

I ran apt-get remove php5 and reinstalled it, but the module is still missing.

I'm not a server "ninja" but normally figure this stuff out, and this is leaving me a bit stumped.
