Ouch! `ee-write-string' is in a module of eev that is not loaded by
default... here are two workarounds - I didn't test them, but any of
them should work. first,

  (require 'eev-prepared)

second:

  (defun ee-octal-to-num (str)
    "Convert STR - a sequence of octal digits - to a number."
    (let ((lastv (- (string-to-char (substring str -1)) ?0))
          (rest (substring str 0 -1)))
      (if (string= "" rest) lastv (+ lastv (* 8 (ee-octal-to-num rest))))))

  (defun ee-write-string (str &optional altfile fmode)
    "Write STR to ALTFILE, or to ee-file if ALTFILE is nil.
  FMODE should be either nil or a string containing a sequence of
  octal digits; if it is not nil then do the equivalent of a
  \"chmod FMODE file\"."
    (let ((fname (substitute-in-file-name (or altfile ee-file))))
      (write-region str nil fname)        ; a standard kludge
      (if fmode (set-file-modes fname (ee-octal-to-num fmode)))))

I will fix that in eev in the weekend, and after the fix the
workarounds won't be necessary anymore.

More soon!
