Exactly. So, if you're in this situation, just make sure

- whenever you use GHC, pass it the -L/usr/lib flag

- put --extra-lib-dirs=/usr/lib in ~/.cabal/config

Now Apple's libs will be preferred when linking haskell executables, 
solving the libiconv errors while still allowing macports libs to be used.
