I changed the name of my Arch Linux package from 'fretsonfire-alarian-mod' to 'fofix', so the link has changed. Here's the new link: http://aur.archlinux.org/packages.php?ID=40614

It should be changed on the Linux instructions wiki page and the external links on the homepage. Sorry if this isn't the best place to post this, but I couldn't think of a better place to put it really.

Fixed, thanks!
