You are supposed to use the rsyncd backup method in backuppc with that
setup, not rsync. The difference is that rsyncd expects to connect
directly with a listening rsync daemon, not start one with ss

That's why you want to stick to all packaged modules whenever
possible. Over time, dependencies can change and the packaged
versions will update together. You can probably update a cpan module
to the correct version manually
at you lose the
hardlinks into the pool/cpool directory that next backup run needs to
