No worries. I can wait. Thanks again for your efforts.

I think I see what the problem is. You haven't defined a goal for the source block and ob-prolog doesn't guard for that. It should be easy to fix, but I am not sure if I will be able to do that before next week. If you want you can try to fix it yourself and send a PR on GitHub or a patch here. BTW, should it be (eval-after-load 'org '(require 'ob-prolog)) or (eval-after-load org '(require 'ob-prolog)) . . . org in quotes? I think both should work. I can't check right now as I only have my phone with me right now.

Re: [O] org-babel for prolog
Thanks for your great effort, BTW. Confused by the requirement: ;; To activate ob-prolog add the following to your init.el file: ;; ;; (eval-after-load 'org ;;'(require 'org-prolog)) My Emacs ( 24.5.1) gives an error with this line. I know I'm probably missing something obvious, but what is org-prolog?
