[TxMt] [RSpec] Error in Running Behavior Driven Description

In RSpec file, if I run Command-R, I get the following error:

/Library/Application Support/TextMate/Bundles/Ruby RSpec.tmbundle/ Support/lib/text_mate_formatter.rb:5: uninitialized constant Spec::Runner::Formatter::HtmlFormatter (NameError) from /usr/local/lib/ ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in `require' from /Library/Application Support/ TextMate/Bundles/Ruby RSpec.tmbundle/Support/lib/spec_mate.rb:14 from / tmp/temp_textmate.zl6ZPP:3:in `require' from /tmp/temp_textmate.zl6ZPP:3

I'm using Ruby RSpec bundle from the latest macromates svn repos. I can't find HtmlFormatter class(?).

Any help would be appreciated.
