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 ?
