funcunit/run envjs file not found error?

I just downloaded JavascripMVC 3.2.4 and am walking through the introductory tour of the Cookbook app on Windows 7.

Under "Testing Cookbook", to run headless it says:

js funcunit/run envjs cookbook/qunit.html

But when I run that command, I get:

js: "<command>", line 1: Couldn't read source file "funcunit/run: funcunit\run (The system cannot find the file specified)".

Can anyone help me get through this step? [or does a headless run not work under Windows?  I can push to my Unix VM if I need to - I'm just in evaluation mode and fewer steps...]

thanks,

Roxanne
