I was able to get this to install on my Mac (using Perlbrew and cpanm with the --notest option). Looks like the tests failed here:

# libpcap version 1.3.0 - Apple version 41

#   Failed test ' - checking version string (libpcap version 1.3.0 - A
+pple version 41)'
#   at t/17-lib_version.t line 17.
#                   'libpcap version 1.3.0 - Apple version 41'
#     doesn't match '/^libpcap version (?:\d+\.\d+(?:\.\d+|[^\d.\s]+)?
+|unknown \(pre 0\.8\))$/'
# Looks like you failed 1 test of 2.

There might be an incompatibility issue with the lib versions, but i would try installing without testing or installing by force and see if your code works.
