Textmate RSpec Bundle Error

After installing the Textmate RSpec bundle I started getting this error:

/Applications/TextMate.app/Contents/SharedSupport/Support/lib/builder.rb:86:in `blank_slate_method_added': stack level too deep (SystemStackError) from /Applications/TextMate.app/Contents/SharedSupport/Support/lib/builder.rb:86:in `blank_slate_method_added' from /Library/Ruby/Gems/1.8/gems/builder-2.1.2/lib/blankslate.rb:84:in `method_added' from /Library/Ruby/Gems/1.8/gems/builder-2.1.2/lib/blankslate.rb:104 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' from /Users/jbasdf/projects/red/vendor/rails/activesupport/lib/active_support/basic_object.rb:21 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require' ... 32 levels... from /Users/jbasdf/Library/Application Support/TextMate/Bundles/RSpec.tmbundle/Support/lib/spec/../spec/mate/runner.rb:36:in `chdir' from /Users/jbasdf/Library/Application Support/TextMate/Bundles/RSpec.tmbundle/Support/lib/spec/../spec/mate/runner.rb:36:in `run' from /Users/jbasdf/Library/Application Support/TextMate/Bundles/RSpec.tmbundle/Support/lib/spec/../spec/mate/runner.rb:24:in `run_focussed' from /tmp/textmate-command-31296.rb:3

The solution is pretty simple. Just add this to spec_helper.rb:

 
$:.reject! { |e| e.include? 'TextMate' }
