Hi!

I've running imq on some servers and it works everywhere except the new
machine I just try to set up.

on that machine I get that

tsunami:/usr/src# iptables -t mangle -A PREROUTING -i eth0 -j IMQ
iptables: No chain/target/match by that name

for testing I've added an 1 and get that

tsunami:/usr/src# iptables -t mangle -A PREROUTING -i eth0 -j IMQ1
iptables v1.2.6a: Couldn't load target `IMQ1':/lib/iptables/libipt_IMQ1.so:
cannot open shared object file: No such file or directory

Try `iptables -h' or 'iptables --help' for more information.

here what I've done plus an strace, I don't have a clue what I did wrong,
works on an other debian woody machine so it can't a dist. problem.

tsunami:/usr/src# tar xvzf libipt_IMQ-1.2.6a.tar.gz -C /lib/iptables
libip6t_IMQ.so
libipt_IMQ.so
tsunami:/usr/src# strace iptables -t mangle -A PREROUTING -i eth0 -j IMQ

system data:  debian woody with an 2.4.20 patched with imq-2.4.18.diff-10 AND 
(= tried both) imq-2.4.18.diff-combo-6 (extracted the source for each patch), 
it doesn't work with any of them
