Pragmatical, easy to implement solution, Bastien, thank you very much.


What I was thinking about meanwhile is:
* write an emacs-lisp function to check whether the needed 
variable/function is available
** if not, throw an error
* attach that function to org-babel-pretangle-hook

So now I can choose between two solutions to this problem,
thanks to the list for answering my question.
