1. make sure you're using a recent version of Org-mode, either the latest release or from git, see http://orgmode.org/worg/org-faq.html#Keeping-current
2. start Emacs with the -Q flag (to ensure there is no problem caused by the rest of your config) 3. evaluate the Babel config (require 'org) (org-babel-do-load-languages 'org-babel-load-languages '((perl . t))) 4. if you still have problems, then write back with your version of Emacs, and your version of org-mode (reported with M-x org-version) Hope this helps, flav <flav.justf...@gmail.com> writes: > I am sorry for my misunderstood but > I put (require 'org) in my .emacs and there is no change. > > > > 2012/12/10 Eric Schulte <schulte.e...@gmail.com> > >> As I mentioned in my previous message you have to require Org-mode >> before executing the following snippet.
