You didn't by any chance install xmonad from AUR? Because there is a
package named "xmonad-darcs 20091222-1" and this package has a
dependency to X11-1.5.0.0, which is in [community-testing].
If you really want to use this version you need to set up
[community-testing] in /etc/pacman.conf, refresh the database (pacman
-S --refresh) and install haskell-x11 from it.

However, I'm using [core], [extra] and [community] only. The latter
supplies xmonad and xmonad-contrib in version 0.9-2.1. Does everything
I want. The drawback of AUR packages is that you need to take of any
updates yourself, because AUR doesn't handle those. So if you really
want to use it, but you don't update regularly, your xmonad install
will eventually become older than the one supplied by [community].
Which is why I would recommend you use xmonad from [community].
