Yay, I know what's going on! * The first error messages indicate that GHC complains about your wxWidgets installation being 32bit. This means that you have a 64bit GHC. The solution is to install the wxWidgets library with the +universal flag, i.e. sudo port install wxWidgets-devel +universal It might be that you have to do the same with the dependencies of the wxWidgets-devel port. You can set the +universal flag globally in /opt/local/etc/macports/variants.conf * The undefined symbols are due to two different libiconv, one provided by OS X and one provided by Macports. The solution is to tell GHC to prefer the former ghc --make -package wx HelloWorld.hs -L/usr/lib Both these issues can be avoided by using homebrew. Whether this merely trades them for other issues is another question, of course... Concerning the EnableGUI thing, it will be obsolete very soon. I have submitted a patch to Jeremy who will upload a new version to hackage once he has tested all platforms.
