I'm pretty sure the problem you're seeing is that recent versions of 
zexy and iemlib are built as a single binary (zexy.pd_linux, 
iemlib.pd_linux) instead of individual binaries for each object class. 
This means you have to load the libraries before you can create any 
objects. You can either add them to the start up libraries 
("File->Startup...->New...") or load them explicitly by putting a 
[declare -lib zexy -lib iemlib] in your patch.
