Personally I think this is a bug in ELSE, and would file a bug that it
ought to be buildable against older versions of Pd (even if that means
that some functionality is missing).

I'm creating new objects for multichannel fun and adding multichannel
awareness to old objects, right now there are over 50 signal objects that
are multichannel aware (and counting).

Without 0.54 you'll just have many errors trying to deal with
CLASSMULTICHANNEL

So yup, 0.54 is needed. Sorry I'm always on the bleeding edge
