Instead of using "apply append", which is trying to call append with
more arguments than (your version of?) Gambit can handle, do the
appending recursively, one list at a time. You can use a fold function
to do this, which you can get from SRFI-1, but it's also easy to define
your own, e.g.:
(define (fold-right proc nil lst)
(if (null? lst) nil
(proc (car lst) (fold-right proc nil (cdr lst)))))
Now you can write your program like this:
(fold-right append '()
(filter-map (lambda (or-chain) <rest of the code...>)))

Oh, the humanity. Perhaps someone should refer the sudoku people to:
