instadmg r200 vs my custom .pkg

I'm not having any luck getting my custom user creation .pkg to install with instadmg r200. Anybody else attempting to use r200 and having problems? Do I need to tweak my package builder setup? In this specific test I have specified the destination as / and checked allow custom location. If I install the package using the GUI it works as expected. What are the recommendations for these type of packages?
