Yeah, it works differently in Max/MSP.  As far as I understand it, Max/ 
MSP calls the setup() function for externals in a different way.  Each  
external object has a main() function, so they can't all be loaded  
into the global namespace.  In Pd each external has a unique setup  
function name that is loaded into the global namespace.
