[O] [org-8.0.7] pb with org-anniversary

[Yvon Henel]

hello all

I've just reinstalled org-8.0.7 on emacs-23.3.1 (Ubuntu 12.04)
and I met a problem with the following syntax

%%(org-anniversary 1986 08 17) Cédric a %d ans.

moreover when emacs is in org-mode it does not recognize the function
org-anniversary

any help would be greatly appreciated
