No idea.
Where did you come across this term?

The MIB doesn't get updated. It's a static description of the
structure used to report a given collection of data. Changes
to this structure should be few and far between - otherwise
any applications developed to work with that structure would
need to be reworked.

That's the job of the MIB-specific code within the agent.
(e.g. the perl extension mechanism you mention above).
Or else a C-code handler nodule to interface between the
agent and the underlying subsystem (software application,
hardware, kernel statistics, etc).
Developing this is actually the bulk of the work required to
add support for a new MIB module. Writing the MIB file
itself is the easy part!
