Maybe you could adapt the approach taken by Agda. Agda's Emacs mode is
installed using Cabal plus a small script:

1) The Emacs Lisp sources are installed as data files, using Cabal.

2) A small program called agda-mode is compiled and installed, using

3) If the user runs "agda-mode setup", then the following code is copied
    into the user's .emacs (unless it is already there):

     (load-file (let ((coding-system-for-read 'utf-8))
                     (shell-command-to-string "agda-mode locate")))

    The .emacs file is found by querying Emacs.

4) The command "agda-mode locate" prints out the path to a file which
    sets up the Agda mode (using the Paths_<package name> module).

    Note that if a newer version of Agda is installed, then Emacs will
    (after being restarted) automatically make use of the new version of
    the Agda mode.

The source of agda-mode can be found in Agda's darcs repository:
