Apparently an old version of portage didn't update all of the
metadata properly when it performed the package moves.  This should
correct it:

echo app-misc > /var/db/pkg/app-misc/mc-4.5.55-r5/CATEGORY
touch /var/db/pkg/app-misc/mc-4.5.55-r5
echo net-firewall > /var/db/pkg/net-firewall/iptables-1.2.7a-r3/CATEGORY
touch /var/db/pkg/net-firewall/iptables-1.2.7a-r3

HTH,

Zac
