In the trunk this has been changed. Maybe this change is not
backported to Emacs 23.3? In the trunk it looks like:

(defcustom package-directory-list
  ;; Defaults are subdirs named "elpa" in the site-lisp dirs.
  (let (result)
    (dolist (f load-path)
      (and (stringp f)
           (equal (file-name-nondirectory f) "site-lisp")
           (push (expand-file-name "elpa" f) result)))
    (nreverse result))
  "List of additional directories containing Emacs Lisp packages.
Each directory name should be absolute.

These directories contain packages intended for system-wide; in
contrast, `package-user-dir' contains packages for personal use."
  :type '(repeat directory)
  :risky t
  :group 'package
  :version "24.1")
