Error when I try to make clone of HN in Windows 7: 'rm' is not recognized

问题

I have downloaded Arc 3.1 and Racket to my Windows 7 machine. I have solved many errors as instructed in http://www.arclanguage.org/item?id=12397 Now when I enter (nsv) the following error occurs and localhost:8080 comes out blank:

arc> (nsv)

Sounds like there's something wrong with your cygwin setup. It can't find rm. Should the cygwin binaries be in your path or something?

Also, cygwin should probably be translating /dev/urandom, since C:/dev/urandom doesn't make sense
