Thanks VERY much, Vin, for your help! In addition to your modified test.pl, for the benefit of others here are the minor patches to apply to Net-Pcap-0.17 to get it to compile correctly. Strangely, I did not have to redo step 4 like you had to.

Apply these patches with the same command line option '-p1' as in Vin's original post:

patch -p1 < net-pcap-0.17-makefile.patch
patch -p1 < net-pcap-0.17-stubs.patch

Here is net-pcap-0.17-makefile.patch:
