I reply to myself for the sake of the archives.

Thanks to a blog entry[*] from someone who I own a beer, I learnt  
that you need to download the soap4r tarball. In the tarball there is  
a utility called wsdl2ruby.rb. I executed

   ruby wsdl2ruby.rb --wsdl wsdl_url --type client

and got a few Ruby files that represent the service and its metadata.  
In particular you get a driver named like the service:

   require 'defaultDriver'

   # MyService is generated by wsdl2ruby.rb
   serv = MyService.new

   # ArrayOfstring is defined as child of Array by wsdl2ruby.rb
   ros = ArrayOfstring.new
   ros << "foo"

   # my_method receives an ArrayOfstring
   result = serv.my_method(ros)

It works like a charm!
