I can't load QCMagritte into Phro 2.0

Hi, yesterday i submit to this wiki a question titled: Error: Name not found: Base At today i don't solve the problem. I'm interested to understund the new QCMagritte support, but i can't load it into Pharo 2.0 As Eliot write in <pharo-dev(a)lists.pharo.org> I suspect you have an older, buggy, VM. What does the VM say to -version ( you can view my answer into <pharo-dev(a)lists.pharo.org> ) But Seaside is load and work fine. Now the ((Smalltalk at: #ConfigurationOfQCMagritte) project version: '0.2') load: #( 'Demo' ) erase the error : Error: Name not found: Base MetacelloMCVersionSpec(Object)>>error: MetacelloMCVersionSpec>>resolveToLoadableSpec:forMap:packages: in Block: [^ self error: 'Name not found: ' , aString] MetacelloMCVersionSpec>>packageNamed:forMap:ifAbsent: MetacelloMCVersionSpec>>resolveToLoadableSpec:forMap:packages: MetacelloMCVersionSpec>>resolveToLoadableSpecs:map: in Block: [:req | (self...
