It seems that iptables broke backward compatibility.

Yes. We do depend on libipt and expect the libraries to be in some 
environment variable IPTABLES_LIB_DIR/libipt_%s 
by default (if environment variable IPTABLES_LIB_DIR is not defined) we
look in /usr/local/lib/iptables

in iproute2 we also need to copy over headers into include/libiptc

Pablo - can we not have a backward compat mode to avoid these hassles?

cheers,
jamal
