[Haskell-cafe] Porting GHC to OSX86?

Hi there, Has anyone made any attempt to port GHC to Mac OS X on x86? Wolfgang Thaller’s binary package runs over Rosetta but slow (not surprising). It can not be used to compile a native version either (I got some errors related to machine registers). I tried to do a bootstrap but can't find the ".HC" files mentioned in the manual. They don't seem to be on the download page of GHC. Any ideas? Thanks. Deling
