problems rendering kanren-sourceforge.scm using PLT SSAX/SXML distro

I am trying to learn SXML transformation to XML/HTML by playing with a 
rather straightforward example:

    
http://cvs.sourceforge.net/viewcvs.py/kanren/kanren/kanren-sourceforge.scm

However, I have run into one problem:

(load "try.scm")
 > (load "kanren-sourceforge.scm")
reference to undefined identifier: generic-web-rules

where try.scm is attached (it simply loads every sxml .ss file it can 
find and redefines srv:send-reply to sxml:display-fragments)

And I anticipate several more based on the grepping the library for 
certain other things:

-- universal-conversion-rules will probably not be identified and cause 
problems later
-- signif-tail does not appear to be defined anywhere either

If someone has a suggestion for getting kanren-sourceforge.scm to 
evaluate completely under PLT Scheme, I would appreciate it.

Here are the versions of the SXML files in PLT collect directory:
