I think I'm going to submit this is a perl bug in the end. Turns
out I had a misunderstanding of how the C-library syslog worked,
which carried over into perl. I thought both used inet sockets by
default (which perl is clearly documented to do), and that syslog
-s merely said only listen to things from your local ip (eg, -s
was the same as -a box.ip -a 127.0.0.1).
In reality, the libc syslog only knows how to do unix domain sockets
(see /usr/src/lib/libc/gen/syslog.c, in particular connectlog).
For some reason perl has chosen the opposite behavior as the default,
to do inet sockets. For anyone running any sort of "secure" syslog
this results in failure.
