def*-maybe-enable-compile-time-hack が未定義で error になると思うのですが
どうでしょうか?


この変数の対策だけならこんな感じ.

;;; Hack for "old" byte-compiler; we can't use `eval-and-compile' here.
(require
 (progn
   (defvar def*-maybe-enable-compile-time-hack nil
     "If non-nil, `def*-maybe' macros will do compile-time check.
`def*-maybe' macro normally checks existence of its target function or
variable at load-time.  But if this variable is non-nil at compile-time,
existence of its target is first checked at compile-time, and if exists,
it will emit no compiled code at all!
You should set this variable to non-nil only when you really know what
you are doing.")
   (provide 'pym-compile)))

pym.el 全体を先に load してしまうとしたらこれ.

;;; preload "pym.el" at compile-time.
;; `provide' is evaluated at load-time only.
(provide 'pym-compile)
;; `require' is evaluated at compile-time as well as load-time.
(require 'pym-compile "pym.el")

たぶん前者で十分だと思います.
