You have two different libpcap installed. Can you determine which is
picked up when? I guess not. pcap_set_buffer_size for example is picked
up from the libpcap you build from source, not the one in base. pcap in
base has no pcap_set_buffer_size.

Just out of interest, could you send me the steps you do for snort
2.9.1? On i386 or on amd64? Thanks.
