I will put out a new release and we will see if it builds. You would want mozart/Oz if you wanted a programming language that "supports declarative programming, object-oriented programming, constraint programming, and concurrency as part of a coherent whole." It has a really nice high level distributed programming model too. Unfortunately it seems not enough people do want that to support an active upstream, and I imagine you would be the first ever user on an S390 if you tried it .... cheers!
