[Steve M. Fabac, Jr.]

I have downloaded the gnupg-1.4.1.tar.gz from 
http://mirrors.rootmode.com/ftp.gnupg.org/
as well as gnupg-1.4.1.tar.gz.sig

and followed the steps to verify the
archive by running

gpg --verify gnupg-1.4.1.tar.gz.asc
 (after renaming gnupg-1.4.1.tar.gz.sig to 
    gnupg-1.4.1.tar.gz.asc )

I get:
gpg: Signature made Tue Mar 15 10:29:15 2005 CST using DSA key ID 57548DCD
gpg: BAD signature from "Werner Koch (gnupg sig) <dd9jn at gnu.org>"
