Well the old binaries for Leopard already work on Snow Leopard.  The problem is the code generated by the GHC compiler doesn't create correct 64bit code when invoking gcc, and gcc on Snow Leopard defaults to 64bit code now.  The solution is to use -m32 in the invocation of gcc by default for Snow Leopard, or to make it emit correct 64bit code.

Given all of the above, I don't think there's any "porting" work to be done.

Hm, don't think so, you have to build for a new platform - http://hackage.haskell.org/trac/ghc/wiki/Building/Porting

Well if I build GHC on Leopard from HEAD and then copy it to Snow Leopard would that not work?

If it is closed, it is fixed in the HEAD.

Any ideas how to get hold of a copy of HEAD, when my Haskell compiler currently outputs rubbish?
