This has been probably been asked many times before but auntie google
can't find it if so.

I've just updated my git clone of org-mode to its version
'409913b253de2de1b49f9468a4b77b9292e090c4' from 'ORIG_HEAD' and I've
done
--8<---------------cut here---------------start------------->8---
M-x org-version
--8<---------------cut here---------------end--------------->8---

which now shows

╭────
│Org-mode version 8.2.6 (release_8.2.6-1 @ /usr/local/share/emacs/24.3.93/lisp/org/)
╰────

How do I drop the debian version and stick with the git version please?

I have this as part of my init file.
--8<---------------cut here---------------start------------->8---
;;; -*- emacs-lisp-mode -*- --- init file
;;; mine from 27-11-13. Heavily influenced by http://www.aaronbedra.com/emacs.d/
;; Show errors in this file:
(setq debug-on-error t
debug-on-signal nil
debug-on-quit nil)

(setq load-path (cons "/home/boudiccas/.emacs.d/lisp" load-path))
(add-to-list 'load-path "/home/boudiccas/git/org-mode/lisp" load-path) (require 'org-install)
(add-to-list 'load-path "/home/boudiccas/git/org-mode/contrib/lisp" load-path)
--8<---------------cut here---------------end--------------->8---

Thanks
Sharon.
