svcd functions

So I'm following the instructions for adding a stack summary gadget in the Debugger. Looks like a keen way to define new frobs:

So I copy/paste the code and the debugger says "No FindSymbol" and associated debug functions. But here it says those functions DO exist:

Anybody know what funny checkboxes and .ini files are needed to drag in those functions?

Thanks,

George
