Best way to install php-gtk2 on unix systems?

Hi everyone! I hope someone could point me out the best way to install php-gtk-2 in a unix-like environment (currently running Fedora Core 4), without associating php-gtk with a php-enabled webserver running on the same machine. Even better would be having a stable version of php (not 5.1) integrated with the webserver, with an "isolated" version of php 5.1 exclusively used to fiddle with php-gtk. The best I've got so far was get php-gtk-2 built and installed along with php 5.1, as I've described here: http://gtk.php.net/wiki/PhpGtk2/InstallingOnUnix Hope someone can shed some light on this for me ;) Thanks, -Jp
