Comment (by hape42):

 @ryandesign  thank you for helping

 I did this: sudo port install xorg-server
 a los of messages run through, but no errors. last message:

 "
 Some of the ports you installed have notes:
   xinit has the following notes:
     To use MacPorts' X11 as the default server, install xorg-server, log
 out, and log back in.
