[Moose-dev] loading ozone in moose

I'm try to load Ozone in moose 5.1 but I got the following error: This package depends on the following classes: MalCyclesCoverageAndSort DSMMatrix DSMCellTest DSMCell NumberColoredDSM You must resolve these dependencies before you will be able to load these definitions: weightedSize testWeightedSize doLayerGraphModified .... Does anyone know what happened to the classes that are not found in the newer version because it loaded correctly in Moose 5.0 (Pharo 3.0)? Are these renamed or is there a package not loaded in the latest moose? tx!
