Outdated rather than missing?
That implies that there is an index file somewhere....
   (Maybe under /var/net-snmp?)
The debug flag '-Dmibindex' might help here.


Another thing to try - what happens if you explicitly load the IP-MIB?

Either
        snmpwalk -m +IP-MIB .....
or
        snmpwalk  ....  IP-MIB::ipNetToMediaPhysAddress

Maybe this MIB isn't part of the default list.

Do you have a file snmp.conf  (note - *not* snmpd.conf) somewhere?
Maybe in ~/.snmp or /usr/local/net-snmp/5.5/share/snmp/
   or  /usr/local/net-snmp/5.5/etc   ?

The debug flag '-Dinit_mib' will show the list of MIBs that is being loaded
automatically.
