Subject: Help with some PayPal SOAP code

I am having issues with PayPal's SOAP API layer.  I am using Ruby 1.8.3
in Ubuntu Breezy.

I downloaded soap4r and used the wsdl2ruby.rb to create
'defaultDriver.rb' and other files to map to the PayPal SOAP API.

I am connecting to the sandbox test server with a account and password
and have the certificates and keys in the right spots. 

I am getting this following error returned from the SOAP request:

10006
Version is not supported

The first error 10006 is a PayPal error basically saying what the
following line says.  Version not supported means that I need to set the
version in the Request, but I can't see where to set that in the files
that wsdl2ruby.rb created.  Here is the script I am trying to
run(basically a customer trying to purchase something using the Direct
Payment API method).

The credit card number is fake btw, i am just trying to sucessfully
connect at this point.  I have the correct username/passwords, i ommited
them in my example.

I have taken much of my methods from this howto, but the author uses a
different PayPal API method than I do, and when I run his script, I
cannot set the version either.
