I am trying to run the wsdl2ruby.rb script that comes with the soap4r gem, and get the following errors:
[ral@lap etc]$ ruby /usr/lib/ruby/gems/1.9.1/gems/so
You might also try the new official repo on Github that has this fix, and others applied to the master branch. You'll need to set your Gemfile to use the git repo as such:
gem 'soap4r', :git => 'git://github.com/felipec/soap4r.git'
