Ruby: soap4r - fixing wsdl2ruby for 1.9.3 version

Some time before when I was trying to generate SOAP Ruby client for my project I encountered the problem with soap4r library. The key problem was with Ruby 1.8 and 1.9 versions compatibility. I've found several independent fixes for that:

• soap4r-ruby1.9
• soap4r-ruby19
• rubyjedi-soap4r

and many others. But there were problems with getting them work properly. So, I had to dig into the installed gem code to find out what causes the errors. In particular, I'm getting error like:

[2011-06-09T17:16:01.012268 #10104] INFO -- app: Creating class definition. I, 
[2011-06-09T17:16:01.012268 #10104] INFO -- app: Creates file 'SessionServic e.rb'. F,

Actually I was interested in wsdl2ruby utility which was needed for SOAP client generation. So, what should be done to make it working?
