In Bernt Hansen's Organize your life in plain text he has

(require 'org-babel-init)
(require 'org-babel-ditaa)
(org-babel-load-library-of-babel)

But with my 7.01trans org I get

Cannot open load file org-babel-init

I guess this has to change to

(org-babel-do-load-languages
 'org-babel-load-languages
 '((emacs-lisp . t)
   (ditaa . t)))

I am just guessing something about babel initialization has changed
recently??
