Yes, it's still worth trying. And setting environments

Under some configurations the exact output interface that gets selected
by OpenPGM in the release bundled with 0MQ is a bit unexpected. I had a
fair bit of trouble with this myself.

It might be worth compiling up some of the OpenPGM example programs (in
the OpenPGM source tree) and concentrating on sorting out OpenPGM
configuration without 0MQ around.
