Yes, you’re right.  The patch for “ghc-x11” actually hadn’t been
pushed.  I was able to build xmonad, but I noticed these warnings:

--8<---------------cut here---------------start------------->8---
Configuring xmonad-0.13...
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
package process-1.2.3.0 requires directory-1.2.2.0
package xmonad-0.13 requires directory-1.2.7.0
--8<---------------cut here---------------end--------------->8---

This indicates that we really need to update other packages too.
I’ll push this now and close this bug, but we really need to harmonise
the Haskell packages.
