uninitialized ob-perl variable stops org-mode

[Jerry Leibold]

After updating emacs-snapshot, my .org files no longer opened in org-mode.

*Messages* showed: void-variable org-babel-tangle-lang-exts

One solution was to remove perl from the list of babel languages in my .emacs:
 '(org-babel-load-languages (quote ((emacs-lisp . t) (sh . t) (ditaa . t) (perl . t))))

A better one was:
   # cd /usr/share/emacs/24.3.50/lisp/org
   # mv ob-perl.elc ob-perl.elc-hide
   # gunzip ob-perl.el.gz
   and change one line in the resulting ob-perl.el
       from: (defvar org-babel-tangle-lang-exts)
         to: (defvar org-babel-tangle-lang-exts '())

Thanks for your report. I think you should report that on the org mode project, I can't do anything about it. I'm closing the bug for now, feel free to reopen it.
