gem install kgio 2.9.2 error

Question

guy now when I bundle install my ruby on Rails project it gives me the error

extconf failed, exit code 1

Gem files will remain installed in c:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9
.1/gems/kgio-2.9.2 for inspection.
Results logged to c:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/extensions/x86
-mingw32/1.9.1/kgio-2.9.2/gem_make.out
An error occurred while installing kgio (2.9.2), and Bundler cannot continue.
Make sure that `gem install kgio -v '2.9.2'` succeeds before bundling.

so any one can help me to install gem install kgio -v '2.9.2' in windows 7 ??

when I trying to install it always I got this error

C:\Sites\vp2.0>gem install kgio -v '2.9.2'
