[Pharo-project] Metacello issues on Pharo 2.0

Hi all, I have issues with Metacello on Pharo 2.0 If I load and run tests for the version used in Pharo1.4, it gives: (ConfigurationOfMetacello project version: '1.0-beta.31.1.4') load: 'Tests' Metacello packages shipped with Pharo 2.0 are all packages derived from the latest stable Metacello baseline (1.0-beta.31.1.5) except the MetacelloToolBox. If I load and run tests packages with version described in the latest stable Metacello baseline (1.0-beta.31.1.5), i.e. : Metacello-TestsCore-DaleHenrichs.14 and Metacello-TestsMC-dkh.351, it gives (Pharo 2.0 #20547): So, it seems there are some problems. Do we use the rigth versions of Metacello packages? Regards, Christophe.
