[CentOS] latest clamav update from rpmforge...no joy - CentOS5

Hi group,

An easy question, I'm sure.

I'm trying to update clamav to the new 0.91 version from rpmforge.  I've
v 90.3 installed (through yum).

Executing:
"yum update clamav" returns:
Loading "installonlyn" plugin
Loading "priorities" plugin
Loading "fastestmirror" plugin
Setting up Update Process
Setting up repositories
Loading mirror speeds from cached hostfile
Reading repository metadata in from local files
0 packages excluded due to repository priority protections
Could not find update match for clamav
No Packages marked for Update/Obsoletion


same results for 'yum update clamav.i386'

Even specificity doesn't seem to help:

yum install clamav-0.91-1.el5.rf.i386.rpm
Loading "installonlyn" plugin
Loading "priorities" plugin
Loading "fastestmirror" plugin

Suggestions (and yes, that means pointers to what I've clearly missed
<g>) are welcome.

Thanks in advance and apologies for what is surely a small oversight on
my part,
