So the agent is looking in the correct place (and failing to find any MIBs).
As expected.

Ah - I understand what you're meaning now.
Remember that the MIB files are only used to translate between numeric
OIDs and textual names. They are not involved in actually providing
the relevant management values.
That is effectively hardcoded into the subagent binary.
Please see the FAQ entry
"Do I actually need the MIB files?"
If the MIB files are not installed, the agent will continue to run
quite unaffected.
(Apart from a few places where it actually refers to MIB objects by
name, such as defining the access control views). But in general, the
agent doesn't use MIB files much at all.
The absence of MIB files is more visible with the command-line tools -
snmpwalk and friends. These can also work without the MIB files being
present, but everything will be displayed using numeric OIDs.
You couldn't say
snmpwalk -v 1 -c public -On localhost system
since snmpwalk wouldn't know what was meant by "system".
But you *could* say
snmpwalk -v 1 -c public -On localhost .1.3.6.1.2.1.1
and you'd see basically the same information.
So returning to your original question:

In fact the subagent is *not* parsing the MIB files, but it doesn't
need them to run.
