Have you played with:

    cabal install --extra-include-dirs=/opt/local/include \
                  --extra-lib-dirs=/opt/local/lib ?

Note that you have to compile all of your macports stuff as 32-bit or
universal (/opt/local/etc/macports/variants.conf, uncomment
"+universal") in order for a 32-bit GHC to link with it.
