You can get mc from elkins.org repository. Direct link here from list of repositories for os2008:http://www.gronmayer.com/it/dl.php?id=128
The thing is that it is not appearing in Application Manager, I had to 'apt-get install mc' from xterm (as root), but that should not be a problem for you since you will use mc from xterm anyway, right?
Report please if it works for you. Don't forget to update apt with either Application Manager or apt-get update after adding repository and before trying to install .Should be automatic but you never know
