FreeBSD Port: firewalk-5.0_1

[Michael Scheidell]

Two issues with Firewalk: on FREEBSD 4.x and 5.x

if the old (non libnet-devel) is installed, you will have to manually 
deinstall it prior to firewalk including libnet-devel.

If you don't, you will get this error:

In file included from ../include/firewalk.h:42,
                 from init.c:38:
/usr/local/include/libnet.h:87: #error "byte order has not been specified,
you'l
l"
In file included from ../include/firewalk.h:42,
                 from init.c:38:
/usr/local/include/libnet.h:88: syntax error before string constant
*** Error code 1


once you deinstall libnet 1.0x, and then make install firewall, and 
firewall installss libnet 1.1x you get this:

init.c: In function `fw_init_net':
init.c:156: `BIOCIMMEDIATE' undeclared (first use in this function)
init.c:156: (Each undeclared identifier is reported only once
init.c:156: for each function it appears in.)

patching include/firewalk.h to include bpf.h has its own problems, and 
won't compile.

if you apply this patch, firewall will compile now:
