Problem with running "WEbrick"

Hi After I installed ruby 1.9.2p290(with rubyInstaller) on windows 7 and connected MySQL to it ( I checked it and it worked ) I installed rails then I create a project on

"C:\Users\Amiref\Documents\Sites\simple_cms"

with this order : "rails new simple_cms -d mysql" then when I use "rails server" to run webrick I saw this error on command prompt :

"rails.bat : C:/Ruby192/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!
