I'm not able to run simple following scenario:

  $ cd a_ruby_netbeans_project
  $ find -type f -name *sort*
  ./spec/sorting/sort_spec.rb
  ./lib/sorting/sort.rb
  $ head -1 spec/sorting/sort_spec.rb 
  require 'sorting/sort'

From CLI I run:
  $ ruby -Ilib spec/sorting/sort_spec.rb 
  $ # runs OK, i.e. finds sort.rb as expected

Running sort_spec.rb from NetBeans does not include classpath:

  FINE [org.netbeans.modules.ruby.platform.execution.ExecutionService]: Running:
     (basedir: /home/emdot/NetBeansProjects/RubyApplication17)
    "/space/ruby/ruby-current/bin/ruby
    -r/space/java/netbeans-hg/main/nbbuild/netbeans/ruby2/sync-stdio.rb
    /space/ruby/gem-repo/bin/spec --require
    /space/java/netbeans-hg/main/nbbuild/netbeans/ruby2/nb_rspec_mediator.rb
    --runner NbRspecMediator
    /home/emdot/NetBeansProjects/RubyApplication17/spec/sorting/sort_spec.rb"

And fails with:

/space/ruby/gem-tool/lib/rubygems/custom_require.rb:27:in `gem_original_require': no such file to load -- sorting/sort
  (LoadError)
        from /space/ruby/gem-tool/lib/rubygems/custom_require.rb:27:in `require'

        from /space/ruby/gem-repo/bin/spec:19:in `load'
        from /space/ruby/gem-repo/bin/spec:19

But which actually means that it is not related only to subfolder, but to all specs. Should I file separated issue. P1
or P2? Or it is the same one?
