Comment #4 on issue 3609 by cy.delau...@gmail.com: Integrate RPackage http://code.google.com/p/pharo/issues/detail?id=3609 Ok, it should work now with that: "load rpackage" Gofer new squeaksource: 'PharoTaskForces'; package: 'ConfigurationOfRPackage'; load. (Smalltalk globals at: #ConfigurationOfRPackage) loadDefault. "to be sure that the organizer is initialized before loading anything else:" (Smalltalk globals at: #RPackageOrganizer) initializeDefault. Gofer new squeaksource: 'DelaunayTmpStuffs'; version: 'Monticello-cyrilledelaunay.506'; merge. Gofer new squeaksource: 'DelaunayTmpStuffs'; version: 'MonticelloGUI-cyrilledelaunay.88'; merge. The problem was that Gorfer was sending some messages to RPackage that were only defined for PackageInfo. I will also change the build script
