yes, same problem here. I'm trying this out as one of my Planet CCRMA
users is trying cm and can't get portmidi input to work. 

Rick? 
This used to work. AFAICT *receive-methods* in io.lisp/io.scm is nil and
never initialized, as long as it is nil nothing will happen. None of the
receiver examples work (tried with today's svn and current portmidi and
rts tarballs).
