OK - I'll merge that one in.

Ah yes, I think I've seen that before, but was reluctant to put it in 
as-is in case it breaks other platforms.  As you say, autoconf magic is

That might be helpful, although I don't know if iftop needs root to run 
effectively on Solaris?

In terms of tracking the issue, we need to figure out if pcap is giving 
us the packets and we're erroneously junking them, or if it's simply not 
giving us the packets.

Adding some debug at the very beginning of the relevant packet handler 
(handle_*_packet() in iftop.c. You can add some debug to packet_init to 
find out which packet handler it's actually using.
