Lispbox and Lisp Toolkit on Windows

I am trying Lispbox on Windows 2000 together with the Lisp Toolkit of
Peter Herth. I am new to Lisp. How do I solve the following name
conflict? I don't get the error using Clisp interpreter outside
Lispbox (Emacs).

CL-USER> (load "c:\\lispbox-0.6\\ltk\\ltk")
T

CL-USER> (use-package :ltk)
(USE-PACKAGE (#<PACKAGE LTK>) #1=#<PACKAGE COMMON-LISP-USER>): 1 name
conflicts remain
Which symbol with name "VALUE" should be accessible in #1#?

[Condition of type SYSTEM::SIMPLE-PACKAGE-ERROR]
..... ecc. ecc.

Thanks.
