I am in my yearly fightto get a working combination of operating system (Snow Leopard), compiler version (6.12) , wxWidgets and wxHaskell on my Mac .
I had same problem just know and it seems to be (as described also elsewhere) that Haskell Platform GHC is linked against system's iconv and by using (or having) MacPorts or Fink with their own version you have a conflict. One solution is to get MacPorts a new version of GHC so there will be no need for Haskell Platform GHC installation if you want to use MacPorts: https://trac.macports.org/ticket/25558 (Or you could just change PATH so that it uses MacPorts version.) The other way is that you (for session in which you compile) hide MacPorts or Fink installation. I had this problem with Fink and I fixed this simply by undeclaring environment variables: export -n LD_LIBRARY_PATH export -n LIBRARY_PATH Of course then you cannot use Haskell libraries which require additional libraries not installed on the system (and this is why you install them with MacPorts or Fink). So one way would be to have Haskell Platform versions which link against MacPorts and Fink iconv (or their library paths in general). The other would be probably to implement/document configuration (extra-lib-dir?) that Cabal (or GHC in general) first searches system's library path (those against which GHC was compiled in Haskell Platform) and if lib is not there goes for MacPorts or Fink's library paths?
