I just figured this out, and I am so glad I did because I am using Devise for a production application that is being deployed to Tomcat, and bcrypt was causing me grief. ANYWAY, here's what you do:

  1. Make sure you are using a version of Ruby from RubyInstaller
    • Download and install which ever version of Ruby you want
    • I should mention that I am using Ruby 1.8.7 and have not tested this for Ruby 1.9+
  2. Download the latest DevKit as well from RubyInstaller.
    • Extract DevKit, but do not set it up at this point
  3. Download and install JRuby
  4. At this point, both RubyInstaller Ruby and JRuby should be available on your path
    • A simple check would be is to open a command prompt window and type
      • jruby -v outputs jruby 1.5.5 (ruby 1.8.7 patchlevel 249) (2010-11-10 4bd4200) (Java HotSpot(TM) Client VM 1.6.0_21) [x86-java]
      • ruby -v outputs ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32]
  5. cd to the directory where you extracted DevKit
  6. Type ruby dk.rb init
  7. IMPORTANT: Open config.yml and make sure that both your jruby and ruby installations are listed. If not, ADD them. Save and close config.yml after you're done.
  8. Back in your command prompt window, type ruby dk.rb install. This will install DevKit to all the ruby installations listed in your config.yml. Most important of all, IT WILL ALSO INSTALL IT INTO YOUR JRUBY INSTALLATION!

  9. Once installation is done, give it a whirl by typing jruby -S gem install bcrypt-jruby

    C:\>jruby -S gem install bcrypt-ruby --no-ri --no-rdoc
JRuby limited openssl loaded. http://jruby.org/openssl
gem install jruby-openssl for full support.
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...

BINGO! BANGO!

bcrypt-ruby now comes with pre-built java gems as of 3.0.1, so you won't need to compile your own to get up and running with Rail 3.1
