Hi, I am using Ruby 1.9.3 and Rails 3.2.1 on Windows 64-bit machine. After following Ryan's step of adding gem 'twitter-bootstrap-rails' to my gemfile and running bundle, I get an error shown below. Any ideas on how to correct this please ?

Installing libv8 ( with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    >c:/Ruby193/bin/ruby.exe extconf.rb

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
