Just double check you're not linking against the wrong things.The
process would be:

    darcs get --partial X11-extras
    configure (check it finds Xinerama)
    build that

    get an fresh xmonad from darcs
    configure ; build ; install

See the mailing list recently for another case of Xinerama being lost
due to linking against old versions of libs,


(Note that nothing's changed that would break Xinerama handling, so its
alsmot certainly due to linking against the wrong version of the lib.
runhaskell Setup.lhs clean is advised for any change in dependent
libraries, like X11-extras).
