You probably need to edit your ip_tables.h file.  Scons should have refused to
try compiling the firewall, but maybe that logic is broken on your system.

                 print "\nWARNING: Netfilter include files are broken or do not exist."
                 print "  This means the Linux firewall support will not be compiled in."
                 print "  To fix, you may edit: /usr/include/linux/netfilter_ipv4/ip_tables.h"
                 print "  line 222 or so, to look like this:"
                 print "  /* Helper functions */"
                 print "  static __inline__ struct ipt_entry_target *"
                 print "  ipt_get_target(struct ipt_entry *e)"
                 print "{"
                 print "        /* BEN:  Was void* */"
                 print "        return (struct ipt_entry_target *)((char*)e + e->target_offset);"
                 print "}"
                 print "\nYou will also want to edit similar code around line 282 of:"
                 print "/usr/include/linux/netfilter_ipv6/ip6_tables.h"

Thanks,
Ben
