As you may have noticed by now, Emacs modes will usually end up in your
profile, normally under `~/.nix-profile/share/emacs/site-lisp'.  Thus,
all you need to do is to add the following to your `.emacs':

  (setq load-path
        (cons (concat (getenv "HOME") "/.nix-profile/share/emacs/site-lisp")
              load-path))

Once that is done, `(require 'haskell-mode)' (or whatever it's called)
should work.

Hope this helps,
Ludovic.
