[bug] void-function org-babel-named-data-regexp-for-name

["Sebastien Vauban" <wxhgmqzgwmuf-geNee64TY+gS+FvcfC7Uqw@public.gmane.org>]

Hello,

When exporting a document containing calls to code blocks located in my LOB
(here: `vc-indicator'), I have -- with latest Org version -- a new problem (I
mean, it wasn't there a couple of days ago):

  Debugger entered--Lisp error: (void-function org-babel-named-data-regexp-for-name)

It seems to me that there is a missing (require 'ob) in org-export (?).

Loading manually `ob.el' does solve that particular problem.

Best regards,
Seb
