This sounds like cabal-macosx was not updated to handle dynamic GHC
libraries. (GHC used to default to static; OS X was one of the first
platforms to switch to default dynamic.) I know in theory how to deal with
this (copy the necessary libraries into the app bundle and use
install_name_tool to adjust the references to be bundle-relative) but could
not give you exact details.
