Thanks Eric... I should have included that my .emacs file has the following
(which I followed from here:
http://orgmode.org/Changes.html#ob-configuration-changes):

;; setup ditaa
(setq org-ditaa-jar-path "~/.elisp/org.git/contrib/scripts/ditaa.jar")
(org-babel-do-load-languages
 'org-babel-load-languages
 '((ditaa . t)
   (gnuplot . t)))
(require 'ob-ditaa)

If I understand correctly, the (ditaa . t) and (require 'ob-ditaa) are
redundant but since it wasn't working, I tried both. Is this what I need to
have babel work with ditaa?

Thanks for any input...
John
