[Moose-dev] ClusterFinder broken?

Dear list, today I installed Moose, and, on top of that, ClusterFinder, which would simply refuse to work - sometimes it will choke on a "Subscript out of bounds" immediately, sometimes it will show a growing progress bar and then complain about the message #writeStream not being understood (while, at the same time, "errorr!a CodeFoo.Deprecation" messages appear). I installed the most recent versions of Moose and ClusterFinder. What do I have to do to make this work? Best, Michael
