Bundler skips eventmachine gem on Win7x64-Collection of common programming errors

I’ve installed Ruby200-x64 via installer and DevKit via self extractor and ruby dk.rb install:

C:\Ruby200-x64\devkit>ruby dk.rb init
Initialization complete! Please review and modify the auto-generated
'config.yml' file to ensure it contains the root directories to all
of the installed Rubies you want enhanced by the DevKit.

Then I’ve added - C:\Ruby200-x64 into config.yml

C:\Ruby200-x64\devkit>type config.yml
# This configuration file contains the absolute path locations of all
# installed Rubies to be enhanced to work with the DevKit. This config
# file is generated by the 'ruby dk.rb init' step and may be modified
# before running the 'ruby dk.rb install' step. To include any installed
# Rubies that were not automagically discovered, simply add a line below
# the triple hyphens with the absolute path to the Ruby root directory.
#
# Example:
#
# ---
# - C:/ruby19trunk
# - C:/ruby192dev
#
---
- C:\Ruby200-x64

C:\Ruby200-x64\devkit>ruby dk.rb install
[INFO] Updating convenience notice gem override for 'C:/Ruby200-x64'
[INFO] Installing 'C:/Ruby200-x64/lib/ruby/site_ruby/devkit.rb'

Then I’ve installed bundler:

C:\Ruby200-x64\devkit>gem install bundler

Then I’ve tried bundle install some app with this Gemfile:

if RUBY_PLATFORM.downcase.include?("mswin") || RUBY_PLATFORM.downcase.include?("mingw")
  gem "win32console"
end

No any error but there is no eventmachine:
