Comment (by raimue):

 The complicated part is not ghc, but writing ports for all of haskell-
 platform. Homebrew does not provide haskell-platform, therefore they only
 have to care about bootstrapping ghc itself. That also means they do not
 model the dependencies of pandoc in the formula, they just rely on cabal.
 This approach is not reproducible (no control over what cabal will
 install) and therefore not the way we want things to be working in
 MacPorts.
