Issue 80: xmonad 0.4 won't install with X11-1.3.0 and X11-extras-0.4 without modifying xmonad.cabal http://code.google.com/p/xmonad/issues/detail?id=80 Comment #1 by 3lucid: I also ran into this on Debian GNU/Linux on a PPC Apple Powerbook G4. What I did was unregister X11-1.3.0, build and register X11-1.2.3, reregister X11-extras-0.4, and modify xmonad.cabal to specify the 1.2.3 version of the X11 module. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
