>Description:
If you run

    /usr/bin/pcap-config --libs

it prints

    -L/usr/lib  -l@PACKAGE_NAME@

It *should* print

     -L/usr/lib  -lpcap

Perhaps the build process isn't doing the "replace '@{config-variable-name}@' with the value of the config variable in question" process that it should do when turning pcap-config.in into pcap-config.
>How-To-Repeat:
Run

    /usr/bin/pcap-config --libs

from the command line, and see what its output is.
