Hi Sébastien,
I tested 'noarp' on a fresh install of RH7.3 with kernel 2.4.18-3
and seems that that version is missing the following files:
        /usr/src/linux/include/linux/netfilter_arp.h
        /usr/src/linux/include/linux/netfilter_arp/arp_tables.h

I tested it with RH8.0 that contains kernel 2.4.18-14 and it
contains all the required files and on it 'noarp' seems to work ;-)

May be you could upgrade to the kernel 2.4.18-14 or better 
to 2.4.19-x

The standard linux kernel 2.4.19 contains 'netfilter_arp' so
'noarp' should work on any distribution with that kernel.

I updated the documentation in 'noarp 1.0.1'.

About the last question: yes, "/lib/modules/`uname -r`/kernel/net/ipv4/"
could be a good place to put the module, but I prefer 
"/lib/modules/`uname -r`/local/" so I know that it isn't a 
standard module.

Ciao 
Maurizio
