hmmm.. i just compiled 1.1.2rc4 but it does not seem fixed to me :(

# ifconfig eth1; ifdown eth1; arping -i eth1 192.168.70.70; ifup eth1

here at debian libnet is compiled also as dynamic library so i did not recompile arping
(my patch to achieve dynamic shareds is always available, just ask) to produce the above
results. recompiling arping as static executable anyway does not change them.
