Tried wine with AliensRL... it kind'a works, but it's unstable as hell sometimes. Besides, wine isn't the proper way to do these things ;-).
I got some fair experience with Linux and compiling as long as Debian and it's derivatives are concerned (meaning also *buntu), so if I could get the source and some build instructions (never compiled freepascal, I usually work with C++) I think I could be able to keep the Linux builds up to date.
