yum update trouble Cannot find a valid baseurl for repo: base

[Neal D. Becker]

I'm stumped.  I have 2 machines.  One (i386) is updating fine from rawhide
-> FC3.  The other x86_64 is saying:

yum update
Setting up Update Process
Setting up Repo:  base
Cannot find a valid baseurl for repo: base

In /etc/repos.d:
fedora.repo:
[base]
name=Fedora Core $releasever - $basearch - Base
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/
mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-$releasever
enabled=1
gpgcheck=1

/etc/redhat-release:
Fedora Core release 3

Even trying yum -d 9 is no more informative.
