The problem is that the libpcap being used by tcpdump isn't DAG- 
enabled for some reason; it's trying to attach to adapter "dag0" using  
BPF, not using the DAG code.

Is HAVE_DAG_API set in config.h in the source directory for the  
libpcap you built?  If so, what does "ldd" print when you run it on  
the tcpdump you built?
