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).

Thanks.
I am totally unfamiliar with gtk. I has assumed that the library installed by
cabal was self-contained. Call me naive....
As you suggested I installed a macports universal variant of gtk2. But it
appears to me that their may be a broader problem, i.e. that I may need to
install universal versions of quite a few macports libraries. I still cannot
build gtk2hs without references to ignoring libraries, and then my sample
program will not link.
I may have to go through and install a bunch of macports universals, but in the
meanwhile I tried installing the 64-bit version of the Haskell Platform. That
installation fails, but does leave a 64-bit version of the ghc framework in the
library. I posted a message about it on the haskell-cafe list, because this too
takes me out of my depth.
Even with the broken installation of 64-bit ghc I get far fewer error messages
when I try to use soegtk with it. It does indeed complain about iconv symbols;
whether that could be remedied is academic if I cannot get a clean installation
of 64-bit ghc, since I have no idea what is broken in 64-bit
After exchanging posts with you I surfed the web a bit, and came to the
conclusion that architecture is something of a problem for quite a few OS X
users of ghc. Is that fair to say?

Yes. For a long time there wasn't a 64-bit GHC at all, and it still throws
a number of warnings and occasional other fits (especially on Lion where
Apple changed the linker yet again, but you're on SL so that at least
shouldn't matter). Also, the HP stuff doesn't play along with MacPorts
very well, and MacPorts' own HP is even older than Debian stable.
Looks like your best bet is to temporarily move /opt/local out of the way
and then follow the directions at
http://live.gnome.org/GTK%2B/OSX/Building#Prerequisites to build native
Gtk+ libraries.

If you're not trying to link against MacPorts it works great, but
MacPorts is the easiest way to install various free software packages.
I haven't tried the 64-bit GHC on OS X in a while.

Well, I just realized that since I only need this for learning purposes (not
production code) I may as well do it under linux. I have my linux box on a kvm
with the mac. (That's my current form of "virtualization" ;-) I'll do this if
ubuntu and HP work well together. Thoughts?

That's where I've ended up for my xmonad development (well, still setting
it up), since xmonad is crashing when I use a ghc that is built against
MacPorts (both MP's own GHC and a locally built up to date
haskell-platform) which I need for X11-xft :/
