Do you actually have devices available?
try doing:
and see if portmidi thinks you have active devices.  For example on  
my machine I get:

         ? (pprint (pm:getDeviceInfo))

         ((:ID 0 :NAME "IAC Driver: Bus 1" :TYPE :INPUT :OPEN NIL)
          (:ID 1 :NAME "828mk2: Midi Port" :TYPE :INPUT :OPEN NIL)
          (:ID 2 :NAME "IAC Driver: Bus 1" :TYPE :OUTPUT :OPEN NIL)
          (:ID 3 :NAME "828mk2: Midi Port" :TYPE :OUTPUT :OPEN NIL))

If getdeviceinfo returns nothing, then use /Applications/Utilities/ 
Audio MIDI Setup.app   and add them (quit lisp first). Sorry im not  
sure what to do on linux...

If getdeviceinfo returns a list of devices then its a bug in CM,  
please send me your list of devices.
