Installing xorg-server will also install its dependency xinit, which installs a launchagent that runs when you log in which sets up the DISPLAY environment variable such that, if you try to launch an X app, the X server will be started first. So "Cannot open display" means that the DISPLAY environment variable doesn't point to a valid display, either because xinit's launchagent isn't running or because you're overriding the DISPLAY environment variable in a shell startup script or somewhere else (if so, remove that override).
Note: See
TracTickets for help on using
tickets.
That means you haven't installed an X server or set it up correctly. Normally it should suffice to install the xorg-server port and follow the instructions it prints, which includes logging out and logging back in afterward.
