I can't reproduce this failure and also the error message doesn't make
sense to me because I added ghc-directory as dependecy to the package.

This error was appearing because Ludo didn't actually apply the patch
for ghc-x11.


I tested both patches again now: they work. I tested them using both

  $ ./pre-inst-env guix build      xmonad ghc-xmonad-contrib # and
  $ ./pre-inst-env guix package -i xmonad ghc-xmonad-contrib

and both worked.

Before building the package, I applied the patch for ghc-x11, then I
applied the patch for xmonad and ghc-xmonad-contrib.
