Isn't this is a problem with the way libraries have loaded by 
default in Pd-ext (I think there's been a long thread about that but 
I haven't followed it)?  I don't know much about zexy's [wrap], but this 
seems a documentation issue rather than a bug-- whether it's at load 
time or in the docs, at some point zexy needs to say, "Greetings, 
gentleman.  All your [wrap] are belong to us."  Or maybe Pd needs to 
say "All my [wrap] are belong to zexy."

If I have a bunch of objects in folder "maxwise-abs," and I tell Pd 
to add that folder to the path, it is extremely likely (99%) that I want 
the abstraction to take precedence over the internal.  (Granted I 
currently only have one object in that folder but I just started...)
