hi, just created this client with wsdl2ruby (via gem). now running the  
client gives me this:

C:\Ruby\00\_Apps\1Client\>ruby CrmServiceClient.rb  
./defaultMappingRegistry.rb:10: uninitialized constant  
SOAP::Mapping::EncodedRegistry (NameError)  
from C:/Ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`gem_original_require' from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’  
from ./defaultDriver.rb:2  
from C:/Ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`gem_original_require' from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’  
from CrmServiceClient.rb:2
