Hi,
I've just tested this with latest RUT240 firmware version and SNMP downloaded from the package manager, snmpd does not return any errors or missing dependencies in CLI.
Please make sure you have the latest firmware version and you're using the SNMP from the package manager.
We're not responsible for any third-party packages downloaded from opkg, as they might be not compatible or we already have some kind of fork of that package installed, so it could conflict.
