[pluggo] plugconfig package data?

I've made some plugins...
They work fine in Ableton Live 5.2 on an Intel Mac.
But on a G4, the midi input data isn't passed from Live to the plugin.  The functionality of the plugin works fine, but doesn't receive data from the pp objects.

I'm getting an error in the max window, package undefined.
On the Intel Mac, there is no error.

The package is defined in plugconfig as ????
If I delete the package line, the next time i open plugconfig, it's there again.  If I change ???? to 0 or 1, it says that value isn't allowed.  What does all this mean?  Is this why midi data isn't being passed or is there another problem?
