--->  Fetching XFree86
Error: Target org.macports.fetch returned: 
            
                    You have an Apple X11SDK installation already.
                        MacPorts will not overwrite it. 

                    If you wish to use Apple X11,
                        install it from your MacOSX install disc.

                    If you really want to use XFree86 instead,
                        please move it aside first :

                            sudo mv /usr/X11R6 /usr/X11R6.apple
