GHC only supports building 32-bit on OSX, but gcc on Snow Leopard defaults to 64-bit. You need to build universal variants of libraries you want to link in Macports (and their dependencies). I think this is enabled by port install ffmpeg UNIVERSAL=1 although you'll need to force ffmpeg (and everything it depends on) to rebuild. John
