Here are the steps given in the files

[start references]

[1. http://arclanguage.org/install ]

1. Install version 372 of MzScheme. (Don't use the latest version. Versions after 372 made lists immutable.)

2. Get http://ycombinator.com/arc/arc3.tar and untar it.

3. Type mzscheme -m -f as.scm and you should get an Arc prompt.

4. If you ^C an Arc program, you'll get the Scheme REPL. Use (tl) to get back to the Arc REPL.

5. If you have questions or suggestions, post them on the forum.

[2. how-to-run-news]

To run News:

tar xvf arc3.tar

cd arc3

mkdir arc

echo "myname" > arc/admins

mzscheme -f as.scm

at the arc prompt:

(load "news.arc")

(nsv)

go to http://localhost:8080

[end references]

I followed the steps, but this is the output that I get

$mzscheme -m -f ac.scm

> (load "news.arc")

reference to undefined identifier: declare

> (nsv)

reference to undefined identifier: nsv

Can someone point out where I am going wrong? I get nothing at localhost:8080.
