Fix issues with correct ruby-debug include for 1.8 vs. 1.9 compatibility.
Also, group all development gems into a development group so jeweler will auto-generate the gemspec correctly.
source "http://rubygems.org"
group :development do
gem 'rake'
gem 'jeweler'
gem 'rspec', :require => 'spec'
if RUBY_VERSION < "1.9"
gem 'ruby-debug'
else
gem 'ruby-debug19'
end
end
