Ok!!, Thanks to Oficial Communities like rubyonrails.org, www.debian-administration.org
This is going to be better
http://wiki.rubyonrails.org/rails/pages/RailsOnDebian
( It's up to date [Updated on October 09, 2008 21:55 by Ben Carpenter] )
And
http://www.debian-administration.org/articles/329
I have a new installation of my debian now.
You have to make previous steps remove the software installed.
#aptitude update
#aptitude upgrade
#aptitude install rubygems
#aptitude install build-essential
Now gem is running from everywhere, # or $.
( RubyInstaller http://rubyinstaller.rubyforge.org, but not now. )
gem install rails --include-dependencies ( so similar to debian apt-get, perfect!! )
( Just to see: MySql Ruby Driver http://www.tmtm.org/en/mysql/ruby/, but it is in gem )
( Just to see something else: Ruby::DBI http://ruby-dbi.rubyforge.org/
http://ruby-dbi.rubyforge.org/rdoc/index.html
#gem install dbi
#gem install dbd-mysql )
Keeping Rails Up-To-Date
#gem update rails
now installing mysql in lenny.
http://maximilianou.blogspot.com/2008/10/debian-lenny-amd64-mysql.html
#aptitude install libmysql-ruby
#aptitude install ruby
This have to return true:
#ruby -e 'puts require "mysql"'
This have to return error:
#ruby -e 'puts require "postgres"'

Problem with the instructions and de version of rails.
I'm not going to work with older versions.
So let's read Web Development.. fast and search other solutions after that.
