[Pharo-project] problem with metacello in 1.2

Hi all, i was trying to make Moose loadable into a 1.2 i did try to run the configuration of Moose and i got an error at the very beginning caused by the configuration of metacello. Am i missing something or it actually should work? I did expect to have problem but not with the configuration of metacello. I'm using a Pharo image 12203 on a Squeak4.2.5beta1U VM To reproduce the error just open the image and execute in a workspace: Gofer new squeaksource: 'Moose'; package: 'ConfigurationOfMoose'; load. (Smalltalk at: #ConfigurationOfMoose) perform: #loadDefault Attached the log. Thanks, Fabrizio
