Which means that your environment has the DISPLAY variable set to ":0" 
which indicates the first display on the local physical machine, or at 
least it would on most platforms that support X11. On a Mac, it's much 
more complicated and your DISPLAY should be a pathname to a socket in a 
subdirectory of /private/tmp/, whose use triggers the startup of the X 
display server and window manager (/Applications/MacPorts/X11.app.)

Make sure you have the xinit port installed (you should, as the 
xorg-server port depends on it.) Also make sure you have logged out and 
back in after installing xorg-server (and its dependencies like xinit.)
