Question

What version/dialect/implementation of LISP is this meant to run on?

(I do understand that the book is written in Common LISP (as specified in the introduction) and that it predates the 1994 CL standard).

Split question into two to make it clearer.

Answer 1

If we look at auxfns.lisp found on Peter Norvig’s web page for the book, there’s this bit

(eval-when (eval compile load)
  ;; Make it ok to place a function definition on a built-in LISP symbol.
  #+(or Allegro EXCL)
  (dolist (pkg '(excl common-lisp common-lisp-user))
    (setf (excl:package-definition-lock (find-package pkg)) nil))

  ;; Don't warn if a function is defined in multiple files --
  ;; this happens often since we refine several programs.
  #+Lispworks
  (setq *PACKAGES-FOR-WARN-ON-REDEFINITION* nil)

  #+LCL 
   (compiler-options :warnings nil)
  )

which suggests its supposed to work in Franz Allegro, Lucid Lisp, or Lispworks
