What about this:

(defun get-last-message ()
  "Try to get the last message."
  (interactive)
  (with-current-buffer "*Messages*"
    (goto-char (point-max))
    (forward-line -1)
    (clipboard-kill-ring-save (line-beginning-position) (line-end-position))))

(add-hook 'post-command-hook 'get-last-message)
