Problem in developing first application in Ruby application

Hi,    I am a new guy in Ruby on Rails. Today I am trying to develop a simple web application by making use of JetBrains RubyMine 3.1.1 IDE.    My system configuration regarding Ruby on Rails is :      OS- Windows, Ruby- 1.9.2p180 , Rails- 3.2.1, gem-1.8.15    My folder structure is like :       C:/ruby/rubygem/ApplicationFolderName(named as "Scripting")    I run "gem install mysql" and "gem install mysql2" from command prompt under C:/ruby/rubygem/ , though I did not get the difference between mysql and mysql2. Both the cases I got "1 gem installed", for mysql2("Successfully installed mysql2-0.3.11-x86-mingw32") and for mysql("Successfully installed mysql-2.8.1-x86-mingw32"). Also in Editor, showing to install mysql Drivers which are required for RubyMine to connect to the Database(MYSQL Connector/J(5.1.18)). I install that driver also.

   Now, I create a project having the type "Rails Application" and database is "Mysql". I switch to the "Rails" view. Then try to run this application and get the following error:

    C:\ruby\bin\ruby.exe -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) C:/ruby/rubygem/Scripting/Scripting/script/rails server -b 127.0.0.1 -p 3000 -e development C:/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb:2:in `require': Incorrect MySQL client library version!
