Diagnoses
Initially there was something wrong with the "GeneratePackage" method. (This failed in the smartobject tester tool as well) After we sent the client the latest 4.6.9 PandD cold-fix, some issues were resolved.
Resolution
After we applied the latest 4.6.9 coldfix, there was a still a slew of missing references that caused issues with PandD. After digging through the XML to find the issue areas and fixing the references in the process and the forms, the client was able to create a package successfully.
