Comment:
Just keeping this alive.
We've had a large number of build failures in the latest xmonad relelase
with people upgrading and reinstalling the X11-extras package, but not
running clean in their xmonad directory. GHC then happily continues
compiling xmonad against the old library, leading to type errors.
The api has changed enough that at least this doesn't produce linking
errors, but *lots* of people are falling over this problem. The solution
is always, if they have a build failure, to make clean first.
It is the single most frequently reported problem with xmonad!
See for example this bug report:
http://thread.gmane.org/gmane.comp.lang.haskell.xmonad/2855
