Just to keep things up to date, PHPMac.com has posted this new tutorial on getting Apache 2.2.2 and PHP 5.1.4 compiled and working on Mac OS X 10.4.6.
For anyone that has been wishing to switch to Apache 2 on their Mac, this is the time to do it. PHP 5 has also recently been updated to 5.1.3 and this tutorial describes in detail, the best method to both build and install these programmes on your Mac.
There's compile and install directives for each of the pieces of software, and even a question about libxml there at the end for those having installation issues with it.
