I am using ruby 1.8. File lib/nokogiri/css/parser.y doesn't get processed by racc when the package gets compiled. As a result of that you can't use nokogiri. Quick and dirty workaround: #cd /usr/lib64/ruby/gems/1.8/gems/nokogiri-1.5.0/lib/nokogiri/css/ #racc parser.y -o ./parser.rb Reproducible: Always Steps to Reproduce: 1. emerge nokogiri 2. irb(main):001:0> require 'nokogiri' Actual Results: LoadError: no such file to load -- nokogiri/css/parser from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' from /usr/lib64/ruby/gems/1.8/gems/nokogiri-1.5.0/lib/nokogiri/css.rb:5 from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' from /usr/lib64/ruby/gems/1.8/gems/nokogiri-1.5.0/lib/nokogiri.rb:34 from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:59:in `gem_original_require' from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:59:in `require' from (irb):1 Expected Results: => true emerge -pv nokogiri (just to see the flags) These are the packages that would be merged, in order: Calculating dependencies... done!

Thanks for the report. This has been fixed in nokogiri 1.5.0-r2.
