Question about prescheme tests???

Ive been attempting to run the tests for prescheme
under /ps-compiler/prescheme/test.

Basically, Im having trouble including any other structure other than
prescheme. First I load prescheme by starting scheme48 in the
ps-compiler directory and typing in

,config ,load ../scheme/platform-interfaces.scm     
,config ,load ../scheme/rts-packages-32.scm          
,config ,load ../scheme/prescheme/interface.scm	     
,config ,load ../scheme/prescheme/package-defs.scm  
,exec ,load load-ps-compiler.scm
,exec

 Then I attempt to use define-local-syntax (just like in the  coerce.scm
test under /prescheme/test/) and put the code into the file hello.scm in
the directory ps-compiler

(define-structure hello (export)
  (open  prescheme comp-util)
  (begin
    (define-local-syntax (define-primitive id nargs)
      (let ((args (reverse (list-tail '(z y x) (- '3 nargs)))))
	`(define (,id . ,args)
	   (call-primitively ,id . ,args))))
    ))
I attempt to include comp-util because thats where i located
define-local-syntax, which isn't exported by prescheme. However, once i
attempt to compile by 


(in 'prescheme-compiler
    '(run (prescheme-compiler
           '(hello)
	   '("hello.scm")
	   'fact
	   "hello.c")))

I get the error 

warning: undefined variables [print-undefined-names]
         #{package 348 config}
         comp-util

assertion-violation: undefined variable [global]
                     comp-util
                     config


So how am I supposed to go about running tests which involved importing
stuff from other packages other than prescheme??
