[Pharo-project] Loading Magma in Pharo 1.1

Hi all, I get a warning about dependencies of Flaptab installing Magma with: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMagma'; load. (Smalltalk at:#ConfigurationOfMagma) project latestVersion load: 'Server'; load: 'Client'. Is safe installing anyway? Or there are some better way to install it?
