Best way to install PHP 5.3 without disrupting current 5.2 on Apache

["Michael J. I. Jackson" <mjijackson@xxxxxxxxx>]

Hello all,

I'm looking for the best way to install PHP 5.3 on Mac OSX with Apache. It's my development machine, and I've already got 5.2.4 running smoothly (with MacPorts). I'd like to keep developing with 
5.2.4, but I'm very interested in trying out some of the new features of 5.3.

When I downloaded and installed the 5.3 snapshot, the new Apache module overwrote the old one. Any ideas? Is there some way to install the new module in a different spot and then tell Apache to differentiate between them?

Thanks,

Michael
