 I see no mention of bison in the libpcap portfile, yet it won't install
 without it. Perhaps it should be added as a dependency? Something like:

 depends_build       port:bison

 I'm also attaching the main.log that was output when it failed to build
 libpcap.

 After installing bison, libpcap installed no problem.
