 Looks like it wants to link against {{{libpcap.A.dylib}}} but is not
 finding it universal.

 I didn't know it used that library, off the top of my head.

 Either deactivate the port that provides it (found like this):
 {{{
 port provides /opt/local/lib/libpcap.A.dylib
 }}}

 or reinstall that port +universal to make the build happy.

 In cases like this, it should either be forced to be skipped if present by
 the build, or specifically required for the build (and then will be
 subject to the usual +universal testing mechanisms).
