when I execute Mathieu$ /Users/Mathieu/.gem/ruby/1.8/bin/wsdl2ruby.rb path --wsdl https://www.arello.com/webservice/verify.cfc?wsdl --type client --force
I get

The quick way to do this is to use a tool like curl to get the WSDL into a file and then just ask wsdl2ruby to create your SOAP client using this file. Ruby is much pickier about SSL certificates than the command line utilities and there are ways of using HTTPS in code, but I think you would need to unpick the code in the utility. All you need are the definitions.
This also has the not inconsiderable advantage of allowing you to keep the WSDL you used in your source code control system as a reference.
