You need the following to run PICker:
Linux/UNIX machine, with Prelude installed and running, Loggrep installed and run every day to produce HTML file for PICker, a web site with PHP, and MySQL. And oh yeah, it also uses the Globals class (you can find it also on the Files section of PICker on SourceForge or get it from http://www.phpclasses.org/browse.html/package/225\).
Darn, I almost forgot, it also uses the Ini File Reader class (http://www.phpclasses.org/browse.html/package/204) , which on its turn makes use of the PHP Version Parser class (http://www.phpclasses.org/browse.html/package/221). Download and install these packages also to get a working PICker.
