ghc-7.0.2 on macports wanted

Dear All, we would appreciate a ghc-7.0.2 distribution package via macports, because we intend to make macports packages based on ghc and gtk+2.0. Libraries from the Haskell-Platform would be nice, too. Was macports given up? Via "port pkg" we want to create binary mac packages, however, these packages are only very basic in that they cannot be uninstalled and do not know about their dependencies. Therefore I would also like how to create proper distribution packages. (links are welcome) Thanks Christian
