[Wine] I'm having trouble installing Wine...

[oceanwilde]

I've read and re-read all the install guides that I can find, I've installed MacPorts, xCode and X11, and yet upon attempting to install wine via terminal, I still get the following error message:

sudo port install wine

Would someone please help me to sort out this problem?
I've spent ages trying to figure out what I've done wrong.
