fwbuilder/test/ipt/firewall4.fw.orig
Vadim Kurland 99498dc90b fixes #2664 Update error message when "which" command fails. Generated 
iptables script uses "which" to check if all utilities it uses exist
on the machine.  We should also check if "which" itself exists and
issue meaningful error message if not.
