Aha! Thanks that gave me enough information to locate a post in
ntop-misc that helped.
I need to configure it like so:
./configure LIBS="-lpfring" PPFLAGS="-I/usr/local/include"
LDFLAGS="-L/usr/local/lib -lpfring" --with-ssl=/usr --disable-editcap
--disable-mergecap --with-zlib=/usr --with-net-snmp=/usr
I think I'll post on ntop-misc now and maybe get this added to the wiki.
Thanks again for the help
