If you downloaded the latest version (0.8.3), you can use it directly.

Note, however, that most Linux systems come with libpcap already - and, 
unless you configure Ethereal with a --with-pcap option that points to 
where you've installed the libpcap you've built from source, when you 
compile Ethereal it might use the libpcap that came with the system.

Note also that the libpcap that comes with the system might be good 
enough for capturing 802.11 packets.

And also note that you won't be capturing in monitor mode by default:
