   Well, as the error message says, "node-list-reduce" is undefined.
Before 1.3, [Open]Jade didn't implement a lot of the higher-level
node-list functions from the spec.  So, you can either get OpenJade
1.3, or put in a definition for node-list-reduce, such as:
	(define (node-list-reduce nl p o)
	  (if (node-list-empty? nl) o
	    (node-list-reduce (node-list-rest nl) p
                              (p o (node-list-first nl)))))
