It looks like a bug that may pertain to this was closed today
https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1501

I am still kind of curious why it only affects some systems and not others
(such as any of mine), although I do not install clamav via rpm on any of my
systems. Just for fun I installed the 0.95-1 via rpm on a CENTOS 5.2 box
that I don't normaly have clamav on and it worked fine, the correct symlinks
were there and the unrar functions tested fine. Hmmmm.
