Actually it was adding the agentXSocket directive that got me that far.
Before, it just shot itself in the head. Now at least it stays alive along
with the subagent, but they show no signs of ever communicating. In 5.2.1
they used to talk happily and do snmpwalks and all kinds of nice things. The
"perl do" seems to make no difference in either case - I think it just gets
ignored.

By the way, if you wander through the comments in perl/agent/agent.pm (in
either 5.2.1 or 5.4.1) it suggests setting up a subagent in what looks to me
like just the way my code snipped shows.

Now at least it stays alive along with the subagent, but they show no signs of ever communicating. In 5.2.1 they used to talk happily and do snmpwalks and all kinds of nice things. The "perl do" seems to make no difference in either case - I think it just gets ignored.

Here the agent failed to even try to open an agentx socket.

Here we can see that
a) The agent tries to open a unix socket at /var/agentx/master
b) You do not need the agentXsocket config directive, you needed, as you
  noted, to remove the perl do directive. As for further perl

interactions that is out of my league.
