PHP 5.3 and 5.5

I want to install PHP 5.3 and 5.5 on the same system. Currently I have 5.5 installed, but when I try to install 5.3 next to it, it only compiles 5.5.



I've tried:

./build set php1_release 5.5

./build set php2_release 5.3



When the build is done I get:

PHP 5.5.19 Installed.

And I've tried to use PHP 5.3 but that doesn't work.
