Freely - make your OSX executable very portable. If you plan to distribute your executable and all the relative libraries with less pain, try Freely! It will copy libraries on which your software depends (with dependencies for that libs, I mean recursive resolving) in the specified directory (./lib/ by default) and relocate their paths by modifying the target executable. Please, check the homepage for more inforamtion and complete examples!
