I had the same issue. Fixing this problem was done not by modifying the code as you did, but by installing both: libnfnetlink AND libnfnetlink-devel. Just add EPEL repository and execute: yum install libnfnetlink* -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
