On the Liip blog today Christian Stocker talks about a one-line installer that's been developed to get PHP 5.3 up and working on an OS X 10.6 platform without much hassle. The tool updates everything needed to get a bit more robust version of the language installed and ready for use.

Apple computers and OS X are quite common here at Liip (and local.ch) as developer machines. But while OS X comes with a not-too-old PHP installation, it nevertheless doesn't have everything we need (for example the infamous intl extension) and it's not that easily extendable with self-compiled extensions. [...] Our friends at local.ch took this very dissatisfying situation in their own hands, forked the build-entropy-php script from Marc Liyanage's great entropy work, extended and adjusted it to their (and our) needs.

If you'd like to try out the package on your own systems, you can find it and the full instructions for its use at http://php-osx.liip.ch/. He also points out the actual build part of the process (build-entropy-php) as well as the packager you'll need for it to grab the library updates it needs.
