[Chicken-users] Problem trying to use SSAX

[Taylor Venable]

Hi, I'm trying to use the ssax Egg for the first time, and running  
into troubles with an example taken from Oleg's site: http://okmij.org/ftp/Scheme/remove-markup.scm

When I try to run my code:

--------------------------------------------------------------------

(require-extension ssax)

(define run2
  (lambda (file)
    (let ((p (open-input-file file)))
      ((ssax:make-parser
        NEW-LEVEL-SEED
        (lambda (elem-gi attributes namespaces expected-content seed)
          seed)

        FINISH-ELEMENT
        (lambda (elem-gi attributes namespaces parent-seed seed)
          seed)

        CHAR-DATA-HANDLER
        (lambda (string1 string2 seed)
          (let* ((seed (cons string1 seed)))
            (if (string-null? string2) seed
                (cons string2 seed))))
        ) p '()))))

(let ((sxml (run2 "request.xml")))
  (display sxml)
  (newline))

----------------------------------------------------------------------------

I get this error:

I can't see the problem in my code, if there is one; I'm just starting  
to work with this so any ideas are appreciated.  Thank you.
