I thought I had fixed that before sending my mail. Apparently not.
#$flags_DisposPtr & #$err-printer are not defined by "lispequ.lisp".
ccl::$flags_DisposPtr & ccl::$err-printer are. The example should read:

(defun new-gcable-ptr (size)
  (with-macptrs ((ptr (#_NewPtr size)))
    ; Be careful to cons the gcable macptr after allocating the pointer.
    (%setf-macptr (ccl::make-gcable-macptr ccl::$flags_DisposPtr) ptr)))
