I added a check to see if a patched libpcap is required, and if so,
whether the system libpcap has the patch. If it doesn't have the patch,
the compile will use the built-in libpcap. Please try it (without -m32)
and see if it works. On 64-bit OS X, you should see this in configure
output:

checking net/bpf.h usability... yes
checking net/bpf.h presence... yes
checking for net/bpf.h... yes
checking if libpcap is suitable... no -- BPF_TIMEOUT BIOCSRTIMEOUT bug (64-bit OS X)
