Arch updated Haskell, but not my xmonad and xmonad - contrib. I recompiled xmonad, got a bunch of errors. I then reinstalled my xmonad-git and xmonad-contrib-git, and then recompiled xmonad and only got one error msg, on ToggleStruts, so I removed that, got zero errors, but no Xmobar, sigh... I will dig into it more, but cabal makes that go smoother??
Thanks Ed
