Then you have different version of libpcap in your system, I guess newer version.
You can create a symlink from your existing version to the new one using ln -s <source> <target> command.
usage something like:
ln -s /usr/lib/libpcap<your_version> /usr/lib/libpcap.so.0.8
You can check libpcap version by ls /usr/bin/libpcap*
Obviously, you have 1.4.0-1 version but your libpcap file can be named differently.
