Well, you've still got an issue here somewhere, because if your server
and client libraries came from the same build then they ought to agree
on this without any help from the config file. AFAIK, Debian hasn't
changed their policy about where to put the socket, so it seems like you
must be using a server that didn't come from Debian.

Correct --- "localhost" is an IP-ism referring to TCP loopback
connections. In the Unix-socket world there is no name for the local
machine at all, since that is the whole universe anyway ... all you
need for that is a filesystem pathname.
