devkit

WIth Ruby 187, I had downloaded devkit from http://rubyinstaller.org/downloads and followed the instruction per https://github.com/oneclick/rubyinstaller/wiki/Development-Kit . I had also ensured that devkit is installed properly by following smoke test. I had then tried installing bluecloth (v2.0.10). It had failed with following error: C:\test\typo>gem install bluecloth --platform=ruby Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing bluecloth: ERROR: Failed to build gem native extension. c:/Ruby187/bin/ruby.exe

I am having a number of issues when trying to install ruby and rails. I have tried both without and now after clearing the previous installed versions.

I've been peacefully developing on Windows without adding any gems for a few weeks now and today I decided to do a bundle update, but I cannot get through this gem called therubyracer. I have the devkit installed and it is working according to the documentation's verification procedure. My question is: is there a way to install this gem at all on windows? And is this gem going to be required by rails 3.1 and this is why now that I do a bundle update it is being 'slipped' into the rails 3.0.8 as a gesture of early kick start for future 3.1 migration? EDIT including Gemfile and Gemfile.lock #
