Yes, you've run across an inadvertant problem with the recent release of
X11-1.3.0. To build xmonad 0.4, you should use only X11 1.2.3, and
X11-extras. So you should unregister X11 1.3.0, install X11 1.2.3, and
X11-extras, and then be sure to clean your xmonad build:

    runhaskell Setup.lhs clean

before rebuliding, which should solve any remaining build problem.

Spencer, perhaps we should do a point release of xmonad -- or just get
0.5 out sooner?
