Unable to compile

[robzenn92]

Hi! I am trying to compile the original gherkin gem with:

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin13.3.0]

I downloaded the repo and I followed the following steps:

gem install bundler
bundle install

When I execute rake clean spec I get this error:

mkdir -p /Users/Roberto/Documents/.../cucumber.github.com/api/gherkin/2.12.2/ruby
ragel -R /Users/Roberto/Documents/.../gherkin/tasks/../ragel/i18n/zh_tw.rb.rl -o lib/gherkin/lexer/zh_tw.rb
ragel: more than one input file name was given
rake aborted!

Tasks: TOP => spec => compile => lib/gherkin/lexer/zh_tw.rb

This is the result with the --trace option.

I am running this on a mac with OS X 10.9.4. Can anyone help me? Thanks in advance, Roberto.
