Problem loading ConfigurationOfGlamour lately:

Whenever i try to load ConfigurationOfGlamour in a 20621 Pharo image i get the following error:

Error: Could not resolve: CollectionExtensions [CollectionExtensions-TudorGirba.34.mcz] in /Users/wm/Pharo Images/package-cache

So i can no longer load ConfigurationOfGlamour. I tried 2.4 and 2.5-snapshot and i did also empty my package-cache. No difference. Any idea where the problem lies?
