[racket-users] about 《Revenge of the Son of the Lisp Machine》 Appendix

[Yuki Lee]

https://www2.ccs.neu.edu/racket/pubs/icfp99-ffkf.pdf
I have read this paper.
I encountered a problem when I tried to run the code at the end.
After reading this article, I added at the beginning

#lang racket
(require (lib "unitsig.ss")) ;;<- that's what i added

(define SchemeEsq
  (unit/sig () ;; no exports
(import mredˆ)
;; The repl editor class
(define esq-text%
Then the problem becomes
unit/sig: signature not defined in: mredˆ  
Does anyone know what should I do？I don't know how to solve it. The f1 page 
doesn't work,

thanks for the reply!
I'm sorry I didn't specify the version and OS of the racket, it works very 
well, thank you.

If you wrote a note or blog while reading the code, please share it with 
me, thank you.
