The hpoj package requires(libsnmp.so.5). This is from the "UCD-SNMP compatibility mode" of NET-SNMP and is required because hpoj links against "libsnmp.so.5" instead of "libnetsnmp.so.5". Since UCD-SNMP is no more and this causes conflicts whith third-party packages (upstream net-snmp RPMs for e.g. RHL9) it would be a good idea to link hpoj against "libnetsnmp.so.5" instead of "libsnmp.so.5". The problem may be alleviated by Bug #100489. This of course goes for anything depending on UCD-SNMP compatibility, but kernel-utils (Bug #105846) and hpoj were the only ones I found (`rpm -qa --requires | fgrep libsnmp.so` on an "Everything" install) that had this problem.
And that's what you get for cut&paste-ing... *sigh* *This* problem will of course _not_ be alleviated in any way by Bug #100489. That's only the same issue for the kernel-utils package in Bug #105846.
Will be fixed in the next hpoj build.
