Ok, then what happened is that gtk2hs found the MacPorts Gtk+ libraries,
which were built native/64-bit, and tried to use them in your 32-bit GHC
environment.  (gtk2hs does *not* come with Gtk+ libraries; you have to
provide them from somewhere.)

So, either you need to find some prebuilt 32-bit Gtk+ libraries, or you
need to rebuild the MacPorts libraries to be +universal so they have been
32- and 64-bit variants.  That said, the latter will probably fail with
missing symbols related to iconv (MacPorts' iconv library is not compatible
with Apple's, which is used by the Haskell Platform build).
