elp-instrument-package does not return anything

["Sebastien Vauban" <wxhgmqzgwmuf-geNee64TY+gS+FvcfC7Uqw@public.gmane.org>]

Hello,

For the sake of finding potential bottlenecks in my config, I'm looking back
at elp.

I've the following minimal Emacs config file for the current work:

#+begin_src emacs-lisp
(message "Loading Minimal Emacs...")

;; change the pathnames appropriately!
(add-to-list 'load-path (expand-file-name "~/src/org-mode/lisp"))
(add-to-list 'load-path (expand-file-name "~/src/org-mode/contrib/lisp"))

(add-to-list 'auto-mode-alist '("\\.\\(org\\|org_archive\\|txt\\)$" . org-mode))

;; profile some times...
(when (require 'elp)
  ;; the most important ones
  (elp-instrument-package "org")
  (elp-instrument-package "org-agenda")
  (elp-instrument-package "outline")
  (elp-instrument-package "font-lock")
  (elp-instrument-package "flyspell")
  (elp-instrument-package "ispell")
  (elp-instrument-package "emacs-leuven")
  (elp-instrument-package "calendar")
  (elp-instrument-package "cal-iso")
  (elp-instrument-package "diary-lib")
  (global-set-key "\C-ce" 'elp-results))

(setq org-agenda-files
      (append
       ;; org-directory
       (file-expand-wildcards "~/Personal/*.org")
       (file-expand-wildcards "~/Projects/*.org")))

(defconst em/emacs-load-time-start (float-time))

(org-agenda-list)

(message "Loading Minimal Emacs... Done (in %.2f s)"
         (- (float-time) em/emacs-load-time-start))
#+end_src

Quite simple, no?

Though, for whatever unknown reason, when calling elp-results, I just get info
about font-lock:

Nothing about Org!?

I'm really out of ideas about what to do to get those Org profiling results?
Any idea of what I'm doing wrong (I guess)?

Best regards,
