I was experimenting with the packaging feature of MacPorts, and decided to do a quick-n-dirty package for Freeciv 2.2.1.
The target environment is PowerPC Macs running 10.4.x.
My older packages worked on Intel-based Macs running 10.5.x as well. So feel free to try it out, although your mileage may vary.
The biggest drawback of this package is its size. It weighs in at just under 250MB once installed. Sorry about this, but like I said, it's experimental.
Download it from [url=http://sourceforge.net/projects/freeciv/]here[/url] and give it a whirl.
