wrong GPG key for FedoraLegacy?

[Neil Smith]

RedHat 9
Attempting to use yum for updating a new install of RH 9 according
to directions from http://www.fedoralegacy.org/docs/yum-rh9.php.
So now have
   yum-2.0.3-0.fdr.1.rh90
   gnupg-1.2.1-9
And also did
   rpm --import http://www.fedoralegacy.org/FEDORA-LEGACY-GPG-KEY
with confirmation:
   rpm -qa gpg-pubkey*
   gpg-pubkey-731002fa-400b9109

And also have verbatum yum.conf from that site:

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
#exclude=kernel*

[base]
name=Red Hat Linux $releasever - $basearch - Base
baseurl=http://download.fedora.us/fedora/redhat/$releasever/$basearch/ 
yum/os/
gpgcheck=1

[updates]
name=Red Hat Linux $releasever - $basearch - updates
baseurl=http://download.fedora.us/fedora/redhat/$releasever/$basearch/ 
yum/updates/
gpgcheck=1

yum check-update shows bunches of available updates.

But when running, say,
[root at achem2 log]# yum update grep
Gathering header information file(s) from server(s)
Server: Red Hat Linux 9 - i386 - Base
Server: Red Hat Linux 9 - i386 - updates

I will do the following:
[update: grep 2.5.1-7.8.i386]
Is this ok [y/N]: y
Getting grep-2.5.1-7.8.i386.rpm
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID db42a60e
Error: Could not find the GPG Key necessary to validate pkg  
/var/cache/yum/updates/packages/grep-2.5.1-7.8.i386.rpm
Error: You may want to run yum clean or remove the file:
  /var/cache/yum/updates/packages/grep-2.5.1-7.8.i386.rpm
Error: You may also check that you have the correct GPG keys installed

I get this regardless of the package requested.

Does anyone know what is happening here?
Thanks.  -Neil
