(defun set-alist (symbol key value)
  "Set cdr of an element (KEY . ...) in the alist bound to SYMBOL to VALUE."
  (or (boundp symbol)
      (set symbol nil))
  (set symbol (put-alist key value (symbol-value symbol))))

(defun put-alist (key value alist)
  "Set cdr of an element (KEY . ...) in ALIST to VALUE and return ALIST.
If there is no such element, create a new pair (KEY . VALUE) and
return a new alist whose car is the new pair and cdr is ALIST."
  (let ((elm (assoc key alist)))
    (if elm
	(progn
	  (setcdr elm value)
	  alist)
      (cons (cons key value) alist))))

Those two functions come from alist.el which is included in Apel:

PS: On debian ~$ apt-get install apel should be okay...
