[LIP] Ruby + soap4r - Error in setting soap property

Hi,
In ruby, while accessing my web service, I get the following error
saying at soap/property file, " bad URI(is not URI?):
#<SOAP::Property:0x2a9642af80>" , I am have updated my gems with
soap4r and http-access2, anyone have faced this problem, Plz shed ur
ideas to overcome this problem,

My code is as follows:
require 'soap/rpc/driver'
require 'soap/wsdlDriver'
require 'cgi'
require 'net/http'
#require 'defaultDriver.rb'
wsdl_url = ARGV.shift
$obj = nil
wsdl_url = 'https://myservice.com/webservice/service?wsdl '
user = "test"
pass = "test123"
#obj  = SOAP::RPC::Driver.new(wsdl_url)
$obj = SOAP::WSDLDriverFactory.new(wsdl_url)

I get this error,
Exception `LoadError' at
/usr/local/lib/ruby/1.8/xsd/xmlparser/xmlparser.rb:10 - no such file
to load -- xml/parser
Exception `LoadError' at
/usr/local/lib/ruby/1.8/xsd/xmlparser/xmlscanner.rb:10 - no such file
