yum on Centos 4.6 fails with invalid dependency on sqlite

Hi, I am Centos 4.6 on x86-64. recently when I tried to do a yum -y
check-update this is the output I get

[root@amd64 ~]# yum -y check-update

I have done yum -y clean all
                      yum clean metadata

but still get the same result
