Is there such a thing? planned? I've seen nothing on the download page.

People have muttered about it from time to time, but we don't have an official port. If you're interested, take a look at the porting section in the building guide, here: http://www.haskell.org/ghc/docs/latest/html/building/sec-porting-ghc.htm l and feel free to ask questions, either here or on cvs-ghc@haskell.org.
