That would be really good - I must try and help you out. I haven't done a lot 
recently as I've had back and arm trouble and have been trying to avoid 
typing too much.

In your qtruby program there should be a require 

require 'Qt'

That will load 'Qt.rb' in the top level /usr/lib64/ruby/site_ruby/1.8/ 
directory. That should then load the C extension 'qtruby4.so' with the 
Init_qtruby4() call in it, and inside that function there is an rb_require() 
call to load the 'Qt/qtruby4.rb' source in turn.
