This is a problem, indeed: The autoloads in org-install.el are
generated by the Makefile (i.e. make org-install.el).  The stable
version of Org mode ships with a pre-generated org-install.el and
without recreating this file with Xemacs it won't run.

The =custom-autoload= is created only once for ob-tangle.el:

,----
| ;;;###autoload
| (defcustom org-babel-tangle-lang-exts
|   '(("emacs-lisp" . "el"))
|   "Alist mapping languages to their file extensions.
| The key is the language name, the value is the string that should
| be inserted as the extension commonly used to identify files
| written in this language.  If no entry is found in this list,
| then the name of the language is used."
|   :group 'org-babel-tangle
|   :type '(repeat
|           (cons
|            (string "Language name")
|            (string "File Extension"))))
`----

As this the autoload directive was added deliberately I suppose there
was a reason for this to be there: If this is the case, there seems
not very much we can do about this.  The autoload generating function
in =autoloads.el= always creates a call to custom-autoload with a
third argument.
