Both contain ENTITY-MIB.my, not .txt
--
-- This mib was extracted from RFC 2737
-- Entity MIB version 2

ENTITY-MIB DEFINITIONS ::= BEGIN

nothing, but I think you mean .1.3.6.1.2.1.47.1.1.1.1.11.5000, in which case:

5.4.2.1:
$ /usr/local/bin/snmpget -v 2c -c ROcomm rta .1.3.6.1.2.1.47.1.1.1.1.11.5000                   
ENTITY-MIB::entPhysicalSerialNum.5000 = STRING: JAE1219HEWA

5.6.1 rc2:
/usr/local/bin/snmpget -v 2c -c ROcomm rta .1.3.6.1.2.1.47.1.1.1.1.11.5000
ENTITY-MIB::entPhysicalEntry.11.5000 = STRING: "JAE1219HEWA"
                             ^^

5.4.2.1:
$ /usr/local/bin/snmpget -Dparse-mibs 2>&1 | grep -i directory                            
parse-mibs: Scanning directory /export/home/netapps/.snmp/mibs
parse-mibs: cannot open MIB directory /export/home/netapps/.snmp/mibs
parse-mibs: Scanning directory /usr/local/share/snmp/mibs

5.6.1 rc2:
$ /usr/local/bin/snmpget -Dparse-mibs 2>&1 | grep -i directory
parse-mibs: Scanning directory /export/home/netapps/.snmp/mibs
parse-mibs: cannot open MIB directory /export/home/netapps/.snmp/mibs
parse-mibs: Scanning directory /usr/local/share/snmp/mibs

5.4.2.1:

ENTITY-MIB::entPhysicalSerialNum.5000 = STRING: JAE1219HEWA

5.6:
/usr/local/bin/snmpget -v 2c -c ROcomm rta ENTITY-MIB::entPhysicalSerialNum.5000
No log handling enabled - using stderr logging
ENTITY-MIB::entPhysicalSerialNum.5000: Unknown Object Identifier
