Not sure what I've done wrong, but I build an RPM from source on Centos 
5-2, and installed the latest rules into /etc/snort/rules. I haven't 
done any customizations, so I figured it would pretty much run out of 
the box with the latest rules from here:

http://www.snort.org/snort-rules/?#rules
cp rules /etc/snort/rules -R
cp so_rules /etc/snort/so_rules -R
cp preproc_rules /etc/snort/preproc_rules -R

Everything went great until i test the configuration:

root at ...274... # snort -c /etc/snort/snort.conf

It's a 64 bit machine, and all libs are 64 bit, so do I have an 
incorrect ruleset?

Thanks
