Signing Problem after Moving GPG and Keys

I'm sorry, what I meant to say was that when I test with a test key, gpg
decrypts and says that the file is signed.  Our Vendor, however, says
the file is not signed when they decrypt it.  The follow up to this was
my second message where rolling back gpg to version 1.2.1 fixed the
problem (although I don't understand why).

Please clarify.  You state both that there is "no signature" and also  
that the "signature doesn't pass".  Is there a signature on the file  
or not?
