The error message is, weirdly, giving a suggestion only valid in ghci. What you actually need to do is `cabal install --lib X11`, and similarly for any other packages it reports.
Tried with Cabal.
alain@keitai-kun:~/.config/xmonad$ ~/.cabal/bin/xmonad --recompile
XMonad will use ghc to recompile, because neither
"/home/alain/.config/xmonad/build" nor
"/home/alain/.config/xmonad/stack.yaml
" exists.
XMonad recompiling (forced).
Errors detected while compiling xmonad config:

xmonad.hs:5:2: error:
Could not load module ‘Graphics.X11.Xlib’
It is a member of the hidden package ‘X11-1.10.2’.
You can run ‘:set -package X11’ to expose it.
(Note: this unloads all the modules in the current scope.)
Use -v (or `:set -v` in ghci) to see a list of the files searched for.

Please check the file for errors.
I am ok with ':set -package X11’ but couldn't find the right syntax.
