unsigned packages?

[Mark Derricutt <mark@xxxxxxxxxx>]

So I went out this evening and left yum happilly downloading several 
hundred rawhide rpms and return home to find a screen full of:

> unsigned package //var/cache/yum/development/packages/gnome-utils-2.8.0-5.i386.rpm

for every package....  yesterday I had to install the GPG keys before 
yum would work, now the packages won't even install?

[root@spawn ~]# rpm -q yum
yum-2.1.9-1
