Unbound Prefix failure with wsdl2perl.pl - wcf

Question

I have a WSDL that is automatically generated by a .NET WCF service. I am trying to generate a Perl client from the WSDL using wsdl2perl.pl. It gets through several of the interfaces and objects before it chokes on
C:\strawberry\perl\site\lib\SOAP\WSDL\Generator\Template\XSD\complexType.tt undef error - unbound http found for http://schemas.datacontract.org/2004/07/Microsoft.Practices.EnterpriseLibrary.Logging. Bound prefixes are wsa, soapenc, soap, wsaw, wsap, q2, xsd, wsx, xml, wsa10, q3, xs, wsam, ser, wsdl, tns, msc, q at C:/strawberry/perl/site/lib/SOAP/WSDL/Base.pm line 62
What does this mean? I can't find any documentation on the error. Since the WSDL is auto-generated by .NET, I'm not sure if I can change it. What do I need to do to resolve this error?
The WSDL I point wsdl2perl.pl to is:
