I've pushed a modified commit that generates the .desktop files for
xmonad, and adds the package instead to gnu/packages/wm.scm.
This Xmonad's mod-q does not work as expected, but that isn't a problem
if you like the default configuration ;). Anyhow, some more work will
need to be done to support reconfiguration. I had thought
GHC_PACKAGE_PATH would do what we need, but it doesn't seem to do what
I had thought. Perhaps creating a custom package database for xmonad
to use would work.
Thanks again for the patch, and sorry for the delay in getting it
pushed!
