UCD-SNMP-MIB has two imports:
IMPORTS
    OBJECT-TYPE, NOTIFICATION-TYPE, MODULE-IDENTITY,
    Integer32, Opaque, enterprises, Counter32
        FROM SNMPv2-SMI

    TEXTUAL-CONVENTION, DisplayString, TruthValue
        FROM SNMPv2-TC;


You may want to try importing those two files.  Import them before the
mib you want to use.  The perl snmp_utils module does not follow import
references for you, unlike the net-snmp tools written in C.

I've never needed to include those two files, but I almost always have
to include the CISCO-SMI and CISCO-TC mibs...
