Personally, I would say "Good Luck" with little to no sarcasm. I don't quite get why PHP is seen as a hurdle to running a traditional LAMP stack either. However, its all Open Source, so you are free to do as you will.
There's a developer download on the Linux page. You are basically on your own at that point.
Development package 35 MB The development package contains all files you need if you want to compile other software packages for XAMPP by yourself and the Unix manual pages. Install this package like the normal XAMPP distribution:
tar xvfz xampp-linux-devel-1.7.7.tar.gz -C /opt
MD5 checksum: 594c61beac23868bd358bc0c31fbf1d7
OK, Good Luck, and let us know how it turns out...
