i had similar problems with the iptables libraries under /lib/iptables/
i added them to the DSOs list in the Makefile, as well as the code that
scans through /lib/iptables
to look for required libraries (in addition to /lib and /usr/lib).
it almost works now, but i still have to add manually the following line
before i do a make images.
