trial by fire, rake and DSL issues

gistfile1.txt

So, I cd into my repo, it auto-bundles, all seems good. Here's the Rakefile:


# encoding: utf-8

require 'rubygems'
require 'bundler'
begin
  Bundler.setup(:default, :development)
rescue Bundler::BundlerError => e
  $stderr.puts e.message
  $stderr.puts "Run `bundle install` to install missing gems"
  exit e.status_code
end

# require 'rake/dsl_definition'
require 'rake'

task :default do
  puts "Hello World!"
end

require 'jeweler'
Jeweler::Tasks.new do |gem|
  # gem is a Gem::Specification... see http://docs.rubygems.org/read/chapter/20 for more options
  gem.name = "gsaindexclean"
  gem.homepage = "http://github.com/mtheoryx/gsaindexclean"
  gem.license = "MIT"
  gem.summary = %Q{Gem to automate the pruning of invalid urls in an index.}
  gem.description = %Q{Parses an index dump from a Google Search Appliance, finds invalid URLs, and adds those to the Do Not Index list.}
  gem.email = "drpoindexter@gmail.com"
  gem.authors = ["David Poindexter"]
  # dependencies defined in Gemfile
end
Jeweler::RubygemsDotOrgTasks.new
# 
# require 'rspec/core'
# require 'rspec/core/rake_task'
# RSpec::Core::RakeTask.new(:spec) do |spec|
#   spec.pattern = FileList['spec/**/*_spec.rb']
# end
# 
# RSpec::Core::RakeTask.new(:rcov) do |spec|
#   spec.pattern = 'spec/**/*_spec.rb'
#   spec.rcov = true
# end
# 
task :default => :spec
# 
require 'rdoc'
# require 'rdoc/task'
# RDoc::Task.new do |rdoc|
#   version = File.exist?('VERSION') ? File.read('VERSION') : ""
# 
#   rdoc.rdoc_dir = 'rdoc'
#   rdoc.title = "gsaindexclean #{version}"
#   rdoc.rdoc_files.include('README*')
#   rdoc.rdoc_files.include('lib/**/*.rb')
# end

I run: rake, and I get:

Then, I uncomment line 13 of the rakefile:
require 'rake/dsl_definition'

And run her again, and I get:

davpoind @ DRP-iMac:~/dev/gsaindexclean [git:master] 
→: rake
(in /Users/davpoind/dev/gsaindexclean)
/Users/davpoind/.rvm/gems/ruby-1.9.2-head@global/gems/rake-0.9.2/lib/rake/file_utils.rb:10: warning: already initialized constant RUBY
/Users/davpoind/.rvm/gems/ruby-1.9.2-head@global/gems/rake-0.9.2/lib/rake/file_utils.rb:84: warning: already initialized constant LN_SUPPORTED
Hello World!

Better, but still really frickin' odd and annoying. So I try another command:

davpoind @ DRP-iMac:~/dev/gsaindexclean [git:master] 
→: bundle exec rake
Hello World!

Why on earth is this happening on my machine, but my machine at work, with the same stuff, is able to use just the plain old "rake" command just fine??

Thanks!
