[Snort-users] Fwd: Problem starting snort

There's the data:

Debian: sid.

rc  snort                                         2.7.0-17
                        flexible Network Intrusion Detection System
ii  libpcap0.8                                    1.1.1-6
                        system interface for user-level packet

Now, snort are on inconsistent status (for dpkg) because the start
fails on the configuration process and break all the update. I make
the installation with apt-get package manager. The update will covered
snort, new gcc, some mysql binaries and another libraries. The update
covers, on the network layer, the firewall (working properly after
update them), snort (breaked), netbase, but not libpcap.

For installing snort, i've used before today the default from debian
package (start-stop-daemon --start --quiet --pidfile
/var/run/snort_eth0.pid --exec snort -- -c /etc/snort/snort.eth0.conf
-S "HOME_NET=" -i eth0 > /dev/null

Today, i've added to the configuration the param -v, but the log on
/var/log/daemon.log doesn't have more relevant information of these
