        I ran into this problem too, bet you've just updated your
version of emacs to 18.56 or above, which handles undo stuff
diferently.....Easiest fix is to define your lisp load path
differently for emacs and epoch eg my .emacs looks like -

(defvar running-epoch (boundp 'epoch::version))

(if running-epoch
    (setq-default load-path (list (expand-file-name "~/src/elisp")
                                  "/usr/local/emacs/local-lisp/GNUS"
                                  "/usr/local/emacs/local-lisp"
                                  "/usr/local/emacs/epoch-lisp"
                                  "/usr/local/src/gnu/epoch-3.2/lisp" ))

 (setq-default load-path (list (expand-file-name "~/src/elisp")
                                "/usr/local/emacs/local-lisp/GNUS"
                                "/usr/local/emacs/local-lisp"
                                "/usr/local/emacs/lisp" ) )


)
        Note the last lines of each of the paths.....

I've come across this problem too when I installed emacs 18.57 el-files
in the shared lisp-directory.  If I do load-library of the old rmail.el
it works OK.  I've got no guess to why this is, though!

				Hope this helps

GNU Emacs 18.57 supports a new version of the undo support, one part
of which is the buffer local variable "buffer-undo-list". The Elisp
code that was shipped with 18.57 refers to this variable for undo
information. Unfortunately, this means that you won't be able to use
this code with Epoch 3.2, since it is based on 18.55.

One solution, a variation of which has already been mentioned, is to
change your load path based on whether you're running Epoch or not.
What I do is I have a .emacs that looks like

(if (boundp 'epoch::version)
  (load (substitute-in-file-name "$HOME/.epoch"))
  (load (substitute-in-file-name "$HOME/.gnu-emacs"))
)

All my Epoch startup code is in my .epoch file, and all my GNU Emacs
code in my .gnu-emacs file.
