Error installing stylish-haskell on Mac OS X on Haskell Platform 2013.2.0.0

I get the same error relatively consistently when trying to install the stylish-haskell package off of hackage. The install went swimmingly until it got to installing conduit, which doesn't come anywhere near installing correctly.

The ending of the error message:

        17 warnings and 2 errors generated.
        Failed to install conduit-1.0.8
        cabal: Error: some packages failed to install:
        conduit-1.0.8 failed during the building phase. The exception was:
        ExitFailure 1
        stylish-haskell-0.5.8.0 depends on conduit-1.0.8 which failed to install. 
        yaml-0.8.5.1 depends on conduit-1.0.8 which failed to install.

The full terminal output I get is:

I'm not an expert here, but I think this is caused by Mavericks replacing the standard gcc with a version of clang wrapped with a gcc-semi-compatible wrapper. It make GHC choke from time to time. You can fix it by editing /usr/local/lib/ghc-7.6.3/settings so that the "C compiler command" entry points to a valid gcc.

For instance, I installed gcc 4.8 from Homebrew and then changed the settings line to

 ("C compiler command", "/usr/local/bin/gcc-4.9")
