[erlang-questions] Problem with socket-based distribution example in the "Programming Erlang" book

[Mike Berrow]

Hi,
I am trying to following along with Joe's tutorial on socket-based distribution from "Programming 
Erlang" book.
On page 190 we are asked to start the name server (and the module kvs).

So in the first session, I set up my environment, then do as asked.

Eshell V5.5.4  (abort with ^G)
1> os:putenv("HOME","C:\\Documents and Settings\\mberrow").
true
2> code:add_patha("./socket_dist").
true
3> kvs:start().
true
4> lib_chan:start_server().
lib_chan starting:"C:\\Documents and Settings\\mberrow/.erlang_config/lib_chan.conf"
ConfigData=[{port,1234},
            {service,nameServer,
                     password,
                     "ABXy45",
                     mfa,
                     mod_name_server,
                     start_me_up,
                     notUsed}]
true

That looks happy. And it has found the config file (placed as directed).

So (as directed) I start up the second session (1st adding "./socket_dist" to my code path)
as follows:

Eshell V5.5.4  (abort with ^G)
1> code:add_patha("./socket_dist").
true
2> {ok, Pid} = lib_chan:connect("localhost", 1234, nameServer, "ABXy45", "").
{ok,<0.34.0>}

That looked OK, but immediately in the 1st session, I get
5> server error:{undef,[{mod_name_server,start_me_up,[<0.40.0>,[],notUsed]},
                     {lib_chan,really_start,3}]}

And there I am stuck.

but mod_name_server.beam is sitting right there in ./socket_dist dir with all the others.

Why am I getting 'undef' ?
