Pear and pdo_mysql in Apache2 on Leopard

seems to be a common issue with leopard's php install..folks are looking to add the modules for pdo_mysql and the pear libraries... before you go reinstalling apache and rebuilding php5 from source.. and getting lost in Leopards symbolic links to the php.ini and httpd.conf files..like I did here.. using this PHP Apache Module and it gets especially tricky if you are on a G5 with 64bit architecture... see this post or this one or this one.
