libipt_ROUTE.so missing in package xtables-addons-common in squeeze

Hi, I need to use the --tee function in iptables that comes with the ROUTE module in order to clone copies of incoming packets and copy to another host, but it seems that the functionality is missing from the iptables (v. 1.4.8-3) and xtables-addons-common (v. 1.26-2+b1) packages that are currently available with squeeze. The required library libipt_ROUTE.so does not appear in /lib/xtables with all other addons libraries. Is this a known issue or an oversight? Is there any way of including it without having to build a tainted kernel? Thanks, Bob
