Add anniversary and org-mode

[Richard G Riley <rileyrgdev@googlemail.com>]

I used add anniversary in the agenda and ended up with
something like

%%(diary-anniversary 3 19 2008) John's daughter's birthday.


in my diary file.

But its not showing up in my agenda or my calendar. What could be the
issue here? I even tried "c" in the calendar view to generate the agenda
for that day.
