i've generally found, that if one buying a Mac and one does not want to use Mac OS X(of which some components of the GUI(Aqua) are under non free licenses), either fry the machine and put a GNU/Linux distribution on it or don't use Aqua, install a Free GUI and the other Free app's with along with Darwin. That's the way to go.
Sorry, could not understand what you wanted to convey.
