Not so, as mentioned you just need to make sure /usr/lib is in the link path before /opt/local/lib. Add -L/usr/lib to your build flags for ghc --make, and put:

extra-lib-dirs: /usr/lib extra-lib-dirs: /opt/local/lib

in that order in ~/.cabal/config for cabal build.

This is a very FAQ and needs to be documented somewhere more obvious, I wonder where. cabal-install and GHC release notes ?

As I mentioned in another reply, this worked for me until I tried to link to a macports lib (I think some regex lib) that actually used the macports libiconv (a lot of them don't even if they pull in the dependency). Then I was really stuck because I had dependencies on two different libiconv's, and neither one would link properly.

As such, I consider this a pretty fragile "solution".

Right, therefore I've reopened http://hackage.haskell.org/trac/ghc/ticket/4068 Christian
