Ruby/Rails installation on Windows 64 bit platform

Need to tread carefully if you want to install Ruby 2.0 on Windows 64 bit. Read the Ruby Installer download page carefully and pick up the correct packages.

Need to be careful on the DevKit you choose to install with Ruby Verison.

I successfully tested with following

• DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe
• Ruby 2.0.0-p481 (x64)
