That error only means one thing: it can't find NS in your path. So either you defined your path incorrectly (try "export PATH=/asdf:/asdf/bin:...etc."), or the ns command isn't in what you specified. So modify your path, or make a symbolic link (read "man ln") to NS, to put a link to it in your path.
