Greetings. I have trouble running shell scripts in Babel. I can't even reproduce examples from worg. For example, this piece of org
#+begin_src sh :results drawer cat <<EOF | 1 | 2 |-- | a | b EOF #+end_src from this page http://orgmode.org/worg/org-contrib/babel/header-args.html produces the following error: org-babel-variable-assignments:sh: Symbol's function definition is void: org-babel-get-header I have just pulled the most recent org, that is, release_8.3.4-753-gda4db33. Any tips? Jarmo
