Recent GUMs?

Hi, I'm trying to get my hands dirty with parallel programming, and apparently, GUM and PVM is the safest way to go. I'm only able to find references to gum-4.06, but I couldn't quite get the snapshot to work. Anyway, I just wanted to ask if I'm on the right track here. Perhaps I'd be better off compiling GHC and GUM from the source distribution? Is there a newer GUM than 4.06 (almost two years old by now) available? Are other people using GPH out there, and if so, what tools are you using? While I'm at it, is there an updated MPI port, btw? -kzm -- If I haven't seen further, it is by standing in the footprints of giants
