I have "greped" w3af sources and don't found any link/use of tcpdump. Perhaps could you give us more info (type of scan, etc...) for finding which dependency/plugin is trying to use tcpdump.
you can see this warning only opening w3af
tcpdump is at /usr/sbin/tcpdump Under gentoo within a normal user PATH dont contains /usr/sbin so w3af (seems to be scapy in fact) cant find it. 3 possibilitys - Change your PATH (but as a normal user you can't use tcpdump) - Run w3af as root (booh) - Change your PATH and modify tcpdump to use caps for running it as a non-root user.
