Are you running it as root?

If not, then libpcap will be unable to open any network devices and will
thus be unable to find a suitable device.  (The only way to avoid the
requirement to run it as root is by changing the permissions or
ownership on the "/dev" devices for network interface devices of the
type on your machine to let you open them for reading and writing - and
even that won't help if you're running in promiscuous mode, as it
appears that, at least on some recent versions of Solaris, you have to
be root to run in promiscuous mode.)
