An question about tethereal.【relink】
 

Hi, everyone:

When I try to execute the following command:

tethereal -i eth0 -v -X -F libpcap -f "port 161" &

It errs:

tethereal: Symbol `pcap_version' has different size in shared object, consider re-linking
tethereal 0.9.8, with GLib 1.2.10, with libpcap 0.7., with libz 1.1.4, with Net-SNMP 5.0.6

What is more weird is that this problem occurs irregularly. Sometimes this command works, sometimes don't.

Thank you for your attention and look forward for your reply.
