mode errors ...

Hello !

I wrote last week about a problem to fontify my shell scripts with the 
right mode (prog-mode that I didn't have) and if possible 
automatically. I received some answers that helped me, but I'm still in 
troubles with the "next step" now : I can still not execute the 
prog-modes (M-x prog-modes nor fontify my files).

I have two kind of errors :
- either "File mode specification error: (error "sh-mode")" when I open 
a file and when XEmacs tries alone to find the right mode to use ;
- either "File mode specification error: (void-variable 
allow-remote-paths)" when I open a file and manually force XEmacs to 
fontify it (command : menu Options/Syntax Highlighting/In this buffer).

What can I do ? I saw in the mails list that I'm not the only one to 
have got this error with allow-remote-path, but I haven't really found 
any answer (and as I don't understand a lot about the "elisp", "efs", 
it is still less easy ...).

Thanks in advance to anyone who will answer me !

MORE DETAILS :
I now have "physically" the prog-modes, in the rigth directory 
(/usr/lib/xemacs/xemacs-packages/lisp/prog-modes/), so XEmacs should be 
able to recognize it and use it. I have in my init.el file :

(setq frame-title-format "%S: %f")
(setq initial-frame-plist '(top 1 left 0 width 80 height 55))

(setq minibuffer-max-depth nil)
(setq efs-use-passive-mode t)

(setq interpreter-mode-alist
       (append '(("^#!.*csh"    . sh-mode)
                 ("^#!.*sh\\b"  . sh-mode))
         interpreter-mode-alist))

(setq ksh-mode-hook
             (function (lambda ()
                (font-lock-mode 1)             ;; font-lock the buffer
                (setq ksh-indent 2)
           (setq ksh-group-offset -8)
           (setq ksh-brace-offset -8)
                (setq ksh-tab-always-indent t)
                (setq ksh-match-and-tell t)
                (setq ksh-align-to-keyword t)    ;; Turn on keyword 
alignment
           )))

I tried also in the init.el file this line :
(setq load-path (cons (expand-file-name 
"/usr/lib/xemacs/xemacs-packages/lisp/") load-path))
But it changed nothing and I got the same errors.
