iptables v1.6.1: Couldn't load match `state':No such file or directory

Package description (wikie) says state is implemented in iptables and not a mod. Though I have also installed mods iptables-mod-conntrack-extra, iptables-mod-extra and iptables-mod-ipopt and it is still not working.

Also not sure why there are lots of double entries, though it says state should be there, but it isnt.
