Bundler.require(:default) fails in Rubinius

Question

I have a very simple app, which i tried to run with Rubinius:

Gemfile:

source 'https://rubygems.org
gem 'rake'
gem 'tiny_tds'
gem 'sequel'

lib/database.rb:

require "rubygems"
require "bundler/setup"

Bundler.require(:default)

DB = Sequel.tinytds(:host => 'SQL2012', :user => "Rails", :password => "xxx", :database => "RailsTest")

test/connection_test.rb:

require_relative "../lib/database"

DB.fetch("SELECT TOP 10 * FROM User") do |row|
  puts row.to_s
end

Rakefile:

require 'rubygems'
require 'rake'
require 'rake/clean'
require 'rake/testtask'

Rake::TestTask.new do |t|
  t.test_files = FileList['test/**/*.rb']
end

task :default => :test

This runs fine with MRI 1.9.3 and MRI 2.1.0 but fails with rbx 2.2.2 :

klaus@rails-dev:$ rake test An exception occurred running /home2/klaus/.rvm/gems/rbx-2.2.2@global/gems/rake-10.1.1/lib/rake/rake_test_loader.rb:

You probably need to add bigdecimal or rubysl to your Gemfile. rubinius has gemified their stdlib, causing issues similar to this one.
