Make TextMate run php from a different binary, not the original php

I work with php and postgre, and since the stock php doesn't come with postgre I had to install a different php version. So I installed php5 from this website: http://php-osx.liip.ch It's a quick install, just downloaded php5 and its modules and put them in a different directory, now everything works, except the TextMate's "php run". I couldn't find where TextMate makes the call to the php and I wanna change it, any ideas? Thanks.
