script/server is yelling at you that rubygems is not installed, but
then you said that using 'rails command' manage to create a empty
application.

How did you managed to install Rails _without_ rubygems?
Maybe you used the zip or tgz package available in rubyforge, which
you should have pointed in your first mail:

- I installed ruby using freebsd ports
- I installed rails grabbing the zip package and running setup.
- THEN i get this error message.

Will be cool when users start writting that kind of reports of their
problems, but still we live in  a imperfect world ;-)

Reading the error message:

WARN  TCPServer Error: Address already in use - bind(2)

That means the port used by webrick is already used by another
process, and is impossible to continue beyond that point.

So:

1) install rubygems
2) look what other process/application is using port 3000 (rails
default).
3) fix your dependencies issues (and correct version of them) for
Rails and the gems you're using in your application.

HTH,
