Sorry if I'm just re-stating what you were already answered: Can't you
implement this as a small Scheme procedure?  Something along the lines
of:

  (read-enable 'positions)

  (define (eval-from-file file)
    (with-input-from-file file
      (lambda ()
        (let loop ((sexp (read))
                   (result #f))
          (if (eof-object? sexp)
              result
              (begin
                (format #t "evaluating `~a' from ~a:~a:~a~%"
                        sexp (port-filename (current-input-port))
                        (source-property sexp 'line)
                        (source-property sexp 'column))
                (loop (read) (primitive-eval sexp))))))))

This would certainly be easier for you to maintain.

Thanks,
Ludovic.
