how to install php4 session support on 4.11

[doug]

I have installed from ports: apache-1.3.34_4, php4-4.4.2_1, php4-mysql-4.4.2_1, 
php4-pcre-4.4.2_1, php4-xml-4.4.2_1, pear-1.4.6, pear-Auth-1.2.4.

Taking the default configuration for all the above. This seems to install php 
without session support. Should I backup and build all this into php4 and not 
use the modular ports?

Also I was looking for php4-pear which seems to exist in 6.x but is not listed 
on the website nor is it in my ports tree.

My goal is to supoort web applications with support for pear-auth.
