I am trying to install Wine using MacPorts via terminal, and I get the
following error message upon attempting to get Wine.

sudo port install wine

I already posted on the Wine forums, and was told to look elsewhere. I have
installed MacPorts, xCode, and X11. I'm really not an expert on these
matters, and have no idea what I need to do to fix this.

Any help would be appreciated. Thanks in advance.
