I encountered such a problem when i configure snort_inline-2.6.1.5 with
"--enable-nfnetlink" option ,description of the issue as follows:

I am using libnetfilter_queue-0.0.12 and libnfnetlink-0.0.16 , The
installation process both are "./configure && make && make install"
I do not have to recompile the kernel,because I see that kernel  already 
support the nfnetfilter_queue feature ( at /boot/config-2.6.20-15   ->
CONFIG_NETFILTER_NETLINK_QUEUE=m) .

what wrong with my installation?  and how can i debug it ?
I think my previous question (Segmentation fault and snort_inline stop 
when using namp  ) may be related to the issue
