I haven't dug in, but unless something has significantly changed, ghc needs to bootstrap from a prebuilt compiler that it downloads, and this prebuilt compiler does not run on 10.6.8, so you're out of luck until (at least) we figure out how to bootstrap something from a version of ghc that did run on 10.6.8.
This is not likely to be a small project, but I would be happy to be surprised. You'd probably be better off to see what is calling in ghc and whether that can be turned off -- perhaps it's not really needed.
