I realize LevelPlayingField is not the preferred mechanism to load stuff into Pharo, and it brings along two other things beside Monticello 1.5 (namely, Installer and Launcher). I will try to prepare something suitable for loading Monticello 1.5 into Pharo, but it cannot be a plain SLICE package, due to the Monticello loading problems I explained above. I'll read up at http://code.google.com/p/pharo/wiki/HowToContribute
I'll also see what changes Stef and Lukas made to Monticello as part of Pharo and attempt to merge them.
Before you invest a lot of work, we should maybe discuss first whether we want Monticello 1.5 in Pharo. Personally, I'm sceptic if this is a good idea. I once had a look and although I know MC quite well, I didn't manage to understand the changes made in MC 1.5 within reasonable time. They look pretty hackish and there are a *lot* of them.
You know me :) I trust you. ;) Now if matthew can really separate things and make them cleaner. Else we keep our old version. stef
