It turns out that even an i386 build made on 10.6 won't work on 10.5: http://hackage.haskell.org/trac/ghc/ticket/4996
And even if this is fixable, it won't help, as we'll have to drop 10.5 support in order to support XCode 4: http://hackage.haskell.org/trac/ghc/ticket/5011 If you build GHC yourself then it should work, though.
