that should almost definitely be "/usr/bin/rsync", not "/user/bin/rsync".

Meaning, for local backups of the backuppc server, you can just set

        $Conf{RsyncClientCmd} = '/usr/bin/sudo $rsyncPath $argList';

(note that it's "$argList" in this case, *not* "$argList+" as with ssh).
If you also want to enable automatic restores, you need to set
RsyncClientRestoreCmd (same value, I believe), too, otherwise you can
set it to undef:

        $Conf{RsyncClientRestoreCmd} = undef;

If you are *not* enabling restores, you might want to limit sudo priviledges
for backuppc like this:

        backuppc ALL=NOPASSWD: /usr/bin/rsync --server --sender *

(this would prevent anyone gaining access to the backuppc account from
overwriting arbitrary files - for whatever it's worth). You can include
more of the command (I have '/usr/bin/rsync --server --sender --numeric-ids
--perms --owner --group -D --links --times --block-size=2048 --recursive *'), 
but unless you can also include the directory to back up, that doesn't gain
you much, and if you do, you'll need two entries - one for full backups
including the "--ignore-times" argument and one without (for multiple shares
this gets a bit awkward).

But just "/usr/bin/rsync" should work fine to start with. You can always start
fine tuning once it's working.
