Oh, here better be, 

(setq outline-minor-mode-prefix "\C-o")

as an e.g. of changing the prefix.

Yes. This is why placing (require 'outline) after 
(setq outline-minor-mode-prefix "\C-o") works.

In all, i was saying these two cases, 

;; change prefix successfully, prefix will be changed to "\C-o".
(setq outline-minor-mode-prefix "\C-o")
(require 'outline)

;; change prefix without success, prefix will still be the one
;; defined in `outline.el' as "\C-c".
(require 'outline)
(setq outline-minor-mode-prefix "\C-o")
