Sorry for being slow to answer. From time to time, even I can be
catch back by real life things.

I didn't forget about this bug, your mails are the last ones in my
inbox (I'm using an inbox-zero process).

I also tried without success on my machine at work, an x86-64 running
an old Mandriva system, with Net::Pcap 0.16, libpcap 0.9.1. This bug
seems to be either very tied to the x86 or to a recent version
version of the libpcap.
I've also tried and failed to link Net::Pcap with libpcap 1.0.0,
which is problematic.

I intend to update Net::Pcap.

I've answered Martín's concerns in the CPAN-RT ticket:

So, as you already suggested..

.. I'll add a new function, pcap_perl_settings() to address this

I'll add a note about signals, pointing to the pcap_perl_settings()
I'll also have to fix the problems with libpcap 1.0.0
Close the world, txEn eht nepO.
