[arch] Pacman 3 RC2

[Aaron Griffin]

Ok, the latest and greatest RC is now available:

Instructions are the same as last time.  Either download this or
'pacman -U' it.  If you're running pacman-rc, you need to uninstall
that first.

The package is here:

http://www.archlinux.org/~dan/pacman/pacman-3.0.0-rc2-i686.pkg.tar.gz

Along with PKGBUILD/install file and all that fun stuff.

If you find any problems, please report them here or on the bug
tracker.  I'm pretty sure we got everything from last time.
