x86_64 duplicate packages problem with apt

[robin at bullseye.tv (Robin Mordasiewicz)]

I installed Centos3.4-x86_64 and I notice that I get duplicate packages. 
i.e. I also notice that the duplate packages exist on the cd install as 
well.


[root@bayamo RPMS]# rpm -qa | grep pam_krb
pam_krb5-1.73-1
pam_krb5-1.73-1


when I use apt after downloading from Dag's site it complains about 
duplicate packages after running apt-get update.

I am missing something to get my x86_64 system to update with apt the same 
way i386 system does, Mebbe someone can provide a hint.
