I've done a first cut at a Mandrake RPM package. There's nothing Mandrake-specific except the name, so in theory this would work for any RPM-based system.

Note that this is an i586 arch build instead of i386 or i686 as planned; I'm building the latter two presently and will upload them when they're done.
The thing I need some feedback on is that I specified the Requires parameter listing out what appear to be the dependent libs & etc. I need to know if you try this rpm on your system and it reports that it won't install due to dependency issues. (The adventurous are encouraged to try --force and --nodeps to see if the rpm will work anyway.)
Here's an SRPM, too:
