Hi Lukas, open builder.seaside.st and download an "Installer Script" from the advanced page. This is broken since Installer DNU #http: The generated pattern is (Installer http: 'someurl') install: 'somepackeg' but should be (Installer monticello http: 'someurl') install: 'somepackeg' This will work at least in latest Pharo. Maybe the builder could be extended to have a "Pharo" and a "Squeak" script option. Now the installer is always loaded from pbwiki at the beginning of the script. If in Pharo it would be better to use "ScriptLoader new installingInstaller" which downloads the Installer using Monicello and Squeaksource and allows to still have "Installer" as an MC package. Thx Torsten -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger01
