Yes, one workaround is needed to get ghc-6.10.x working on Snow Leopard:

Simon says:

        Ok, just to summarise the situation:
        6.10.4 needs a tiny fix to work with Snow Leopard: add -optc-m32
        -opta-m32 -optl-m32 to the script /usr/bin/ghc, or wherever ghc
        lives on your system.
        The 32-bit OS X distribution of GHC 6.12.1 will work on Snow
        Leopard without modification.
