Problem running LispWorks from ILISP under Windows

I am trying to run LispWorks Professional for Windows as an inferior
Lisp, but I am getting an error message when I try to compile
something. For example when doing 'M-x ilisp-compile-inits' at first
startup:

--------------------
CL-USER 11 > ;;;Compile c:/elisp/ILISP/lispworks.lisp
;;; Compiling file c:/elisp/ILISP/lispworks.lisp ...
;;; Safety = 3, Speed = 1, Space = 1, Float = 1, Interruptible = 0
;;; Compilation speed = 1, Debug = 2, Fixnum safety = 3, GC safety = 3
;;; Source level debugging is on 
;;; Source file recording is  on 
;;; Cross referencing is on
; (TOP-LEVEL-FORM 1)
; (TOP-LEVEL-FORM 2)
; ILISP:ILISP-EVAL
; ILISP:ILISP-TRACE
"ILISP: The file \"macros/specmac\" does not exist."

CL-USER 12 > 
--------------------

I tried to 'grep' for macros and specmac in the ILISP-directory with
no success. 

Can someone help?

I am having no problems with the Linux version, there it works just
fine. I checked out a version of ILISP from the cvs-repository earlier
in April, I did a cvs update today on my Windows machine just in case.
