在mac上安装php 5.4，更改版本?? （返回旧版本？）

Im trying to update php to 5.4, and I think ive installed it with http://php-osx.liip.ch/. But when i do php -v it says that i have 5.3.15. But if i do /usr/local/php5/bin/php -v it says 5.4.9. Is there something i should change to get 5.4 as default?

here's a pic of Terminal:

(never done this before, sorry if its a stupid question.)

Uninstall the old version of php and make sure that the new versions directory is in the $PATH variable.

typing this in Terminal fixed it for me: PATH=/usr/local/php5/bin:$PATH
