[CM] Problems with CLM on RH 7.3

[David Gerard Matthews]

Greetings,
                I've finally gotten the time to sit down and try to 
learn CLM, but have already gotten into some problems with the tutorial.
I'm running Red Hat Linux 7.3 and cmucl with the Planet CCRMA 
cmucl-cm-clm-cmn package.   When trying to define an instrument, as in:

(definstrument simp (start-time duration frequency amplitude)
  (multiple-value-bind (beg end) (times->samples start-time duration)
    (let ((s (make-oscil frequency)))
      (run
       (loop for i from beg below end do
     (outa i (* amplitude (oscil s))))))))

I get the following error:

"DEFMACRO DEFINSTRUMENT"
 (DEFINSTRUMENT SIMP
                (START-TIME DURATION FREQUENCY AMPLITUDE)
                (MULTIPLE-VALUE-BIND # # #))
 NIL)
Source: Error finding source:
Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM:  Source file no longer 
exists:  /usr/src/redhat/BUILD/clm-2/defins.lisp.

I do not have this file, or even a /usr/src/redhat/BUILD directory. 
 Should it be living somewhere else?  Is it possible that it is 
installed somewhere else on my system?  Is there a file I can edit to 
reflect the actual location where it can be found?

thanks,
dgm
