rails won't go

[Luca Pireddu]

I'm trying out the rails tutorial (http://www.rubyonrails.org/show/Tutorial).
I've reached step six where I get to access my new page but things don't work.
I'm hoping someone can help me figure out what the problem is.

I've tried accessing the page via the WEBrick servlet. I started it with
ruby dispatch.servlet -a
and then pointed my browser to http://localhost:3000/friends/display

I'm greeted with
Not Found

`/friends/display' not found.
WEBrick/1.3.1 (Ruby/1.8.2/2004-11-23) at localhost:3000

On the display WEBrick shows me the following error:

#<WEBrick::HTTPStatus::NotFound: `/friends/display' not found.>

------------------------- end WEBrick error --------------------------

I've also tried with Apache, but I end up with a similar error in the log:

/usr/lib/ruby/1.8/cgi/session.rb:264:in `initialize': undefined method
`create_new_id' for CGI::Session:Class (NoMethodError)

-------------------------- end error msg ------------------

On the other hand, at the browser I'm greeted with the rails 500.html message:

Application error (Apache)

Change this error message for exceptions thrown outside of an action (like in
Dispatcher setups or broken Ruby code) in public/500.html

Here's my setup:
[fidele apache]# gem list --local

*** LOCAL GEMS ***

actionmailer (0.4.0)
Service layer for easy email delivery and testing.

actionpack (0.9.5)
Web-flow and rendering framework putting the VC in MVC.

activerecord (1.1.0)

rails (0.8.5)

rake (0.4.11, 0.4.8)

[fidele apache]# ruby --version

[fidele apache]# apache -version

If there's any other info I should provide let me know. TIA

Sounds like 1.8.2 change the API for CGI::Session:Class. Rails is
currently only verified to run on 1.8.1. But I would like to make it
ready for 1.8.2. Anyone know what changed?

Session.create_new_id has become Session#create_new_id
(http://tinyurl.com/5j7nx). This was reported on Nov 27 [ruby-core:3832],
and fixed on Nov 29 (http://tinyurl.com/3pvrw).

Ahh, okay. So if people see this error they'll have to apply
http://tinyurl.com/3pvrw or update to the CVS version. Gotcha. Thanks!
