lilypond-mode with XEmacs

[Maury Merkin]

Has anyone gotten lilypond-mode to work with XEmacs?  

Here are the pertainant lines from my init.el file:
====  begin ====
(setq load-path (cons "/usr/share/xemacs/21.4.12/site-packages/lisp/lilypond/" 
load-path))
(setq auto-mode-alist (cons '("\\.ly$" . lilypond-mode) auto-mode-alist))
(autoload 'lilypond-mode "lilypond-mode.el")
(gnuserv-start)
====   end   ====

All I get is this message on the status line:
File mode specification error: (error "Autoloading failed to define function 
lilypond-mode")

The file "lilypond-mode.el" is definitely in 
/usr/share/xemacs/21.4.12/site-packages/lisp/lilypond/

address@hidden:/usr/share/xemacs/21.4.12/site-packages/lisp/lilypond> ls 
lily*
lilypond-font-lock.el  lilypond-init.el  lilypond.words.el
lilypond-indent.el     lilypond-mode.el
address@hidden:/usr/share/xemacs/21.4.12/site-packages/lisp/lilypond>


Any suggestions, hints, ideas?

TIA,
