Did you try my checklist?

That will say that for a few more versions of Rails, apparently. It is a
"warning", which in computer science is a minor error that does not stop a
program.

And that is a normal Mongrel startup.

Does your site work? Do your unit tests pass? What is in your log/* folder?
Does log/development.log contain the word Error anywhere?

on your dev machine, point your web browser to
localhost:0.0.0.3000
You should see the Welcome to Rails page.

You also want to make sure you've properly entered the values in your
Yaml file for your system.

But you really should take this to the Rails list or browse more
Rails sites. This point in starting out with Rails is very well
documented in many books and countless online tutorials.
