I don't think this is an Emacs bug. view-mode-map is not defined at
startup in Emacs 23.1 either. You can test this by doing

emacs-23.1 -Q

then immediately evaluating view-mode-map. Many things, including
doing C-h v on a variable will load view.el, so probably something
happens on one system to load it.

If you want to change view-mode-map in your .emacs, you can do it
in various ways:

1)

(eval-after-load "view"
  '(progn
    (define-key view-mode-map ...)
     ...)))

2)

(require 'view)
(define-key view-mode-map ...)
...

3)

(add-hook 'view-mode-hook (lambda ()
   (define-key view-mode-map ...)
     ...))
