Allegro hangs while compiling Cinco de Mayo PCL

[Darrell <shane%blackcomb@rand.org>]

When compiling the boot file, in latest version of PCL under both Allegro
3.0.1 and 3.0.3 the system hangs at the following spot:

; --- Compiling file /b/shane/cl/clos/pcl/new/boot.lisp ---
; Compiling REDIRECT-EARLY-FUNCTION-INTERNAL
; Compiling DEFGENERIC
; Compiling EXPAND-DEFGENERIC
; Compiling LOAD-DEFGENERIC
; Compiling DEFMETHOD
; Compiling METHOD-PROTOTYPE-FOR-GF
; Compiling EXPAND-DEFMETHOD
; Compiling EXPAND-DEFMETHOD-INTERNAL
; Compiling ADD-LEXICAL-FUNCTIONS-TO-METHOD-LAMBDA
; Compiling MAKE-PARAMETER-REFERENCES
recursive format error, would have printed: 
"Funcall of ~s which is a non-function." 
0 recursive format error, would have printed: 
"Funcall of ~s which is a non-function." 
0 

Any help would be appreciated,
