Rails - Jul 2011 - [Windows] I have mysql2 (0.3.6): Rails asks for mysql2 (> 0.2.6) and doesn't start

Hello, I''m really new to the Ruby and RoR world, so first of all, hi to
all ^^

Now to the issue explained from the beginning:
I had already installed a MySQL server (xampp)
I installed Ruby from RubyInstaller.
I installed rails from gem.
I installed the DevKit manually.
I installed a MySQL server to copy the libraries and headers to the
XAMPP MySQL installation.
I created a new Rails project with a MySQL server as default.
I tried to start the Rails server and it says "Could not find gem
''mysql2 (~> 0.2.6, runtime)'' in any of the gem sources
listed in your
Gemfile"
I tried a "bundle install" and failed to find MySQL headers to
compile.
I succefully installed the mysql2 gem that rails asked for specifying
the MySQL libraries and headers paths.
Rails keeps saying that I need the version 0.2.6 or higher of mysql2
I tried adding -v 0.2.6 to the end of the gem install command while
installing mysql2, but it ignored it.

There is any chance someone can tell me what to do now? I''m out of
ideas

By at the end do you mean you did gem install mysql2 -- various build
options -v 0.2.6  ?

if so then that version option is getting passed to the extension
building script, not to gem install. You want gem install mysql2 -v
0.2.6 -- various built options.

By the way, ~>0.2.6 means 0.2.x, with x >= 6 so its normal that if you
only have 0.3.6 things don''t work (the 0.3 series of mysql2 require
rails 3.1)
