A small follow up to this, possibly related to using emacs 23 I dont
know, but I had some load order issues with the keybinding for the w3m
buffer. The following solved it:

,----
| (eval-after-load "w3m"  '(load "manatee"))
`----

Where "manatee" is the code below.

| ;; Code to integrate the w3m article buffer in gnus with org-mode.
| ;; Kudos to Andy Stewart (ManateeLazyCat on #emacs IRC) for provding
| ;; the code following a request. Can now paste w3m regions showing html
| ;; emails and newsletters directly into org-mode buffers with the URLs
| ;; transformed into org links. There is a default M-w key binding included.
| ;; 
| ;; manatee.el for now prior to any integration.
