It's in development along with the Mac OS X version. I believe they are having issues trying to maintain all the different methods for memory management across the 3 different OSes. Since each one does things differently, from what I've read it's not such an easy task.

I guess you could help out if you wanted. Have a read at Eli Boling's blog if you want more information about Linux and Mac OS X support. http://blogs.embarcadero.com/eboling/
