Continuing the work on Pier3AddOns Build, for version 3.2 it partially loads after applying Pier and Seaside 3.2 updates, however it hits an error:
MetacelloProjectSpecLoadError: No version found for #'release3.1' of ConfigurationOfSeaside3
Details show that for Pharo 6.1, this is defined as #notDefined. The error shows up when the progress bar has:
Fetching 3.2.0 of ConfigurationOfPier3AddOns Fetching 0.32-baseline of ConfigurationOfPillar Fetching 1.33 of ConfigurationOfCocoon Fetching 3.5.0 of ConfigurationOfMagritte3
Proceeding through these errors seems to work out OK.
