gpg: public key not found

[David.A.Gustafson at nws02.usace.army.mil]

Quick question: 

I was trying to verify signature file rsync-2.6.0.tar.gz.sig for latest
version or rsync and am getting:

gpg: Signature made Thu Jan 01 11:14:08 2004 PST using DSA key ID 4B96A8C5
gpg: Can't check signature: public key not found

I've checked for this key id but have not found it.  Yes I have imported
samba-pubkey.asc but still not go...  

Thanks in advance,

Dave G.
