[Orgmode] Not Match - When follow Hyperlink

[Csanyi Pal]

Hi,

I have installed on Debian GNU/Linux Lenny
GNU Emacs 22.2.1 (i486-pc-linux-gnu, GTK+ Version 2.12.11)
 of 2008-11-09 on raven, modified by Debian

In emacs-org mode when follow a Hyperlink I get a Message: 'Not
Match'. 

When the file whereof the Hyperlink points is another file.org, then
the file being opened and get the 'Not Match' message, but when the
file is say PDF or DVI I can't to open that file and get the message
'Not Match'. 

I edited the .emacs file:
---------------------->
(defun define-trivial-mode(mode-prefix file-regexp &optional command)
  (or command (setq command mode-prefix))
  (let ((mode-command (intern (concat mode-prefix "-mode"))))
    (fset mode-command
          `(lambda ()
             (interactive)
             (toggle-read-only t)
             (start-process ,mode-prefix nil
                            ,command (buffer-file-name))
             (kill-buffer (current-buffer))))
    (add-to-list 'auto-mode-alist (cons file-regexp mode-command)))
  )

(define-trivial-mode "gv" "\\.ps$")
(define-trivial-mode "evince" "\\.pdf$")
(define-trivial-mode "gschem" "\\.sch$")

;; dvi
(defun view-dvi ()
  "Use evince to view DVIs."
  (interactive)
   (progn
     (toggle-read-only t)
     (start-process "dvi" nil
                    "evince" (buffer-file-name)))
)
(add-to-list 'auto-mode-alist '("\\.dvi\\'" . view-dvi))
-------------------------------->

Is there a way how to open in emacs org-mode a pdf or dvi file with
Evince? 

Any advices will be appreciated!
