No. The chaos, creb and mrpeach binary distributions are part of the
demonstration package for pdlibbuilder, a new build package designed to
replace the template makefile system from pd-extended.
For now, I have enough to do on cyclone. I might submit an occasional
patch if I find an issue elsewhere (like the garray_getarrayfloats()
problems), but do not intend to maintain more libraries for now.

By all means, submit them. Once you have a good description of the
behaviour and its problems, you are more than halfway in fixing the
actual code!
