[Pharo-project] How to load pier in 1.4

Hi I'm updating the configuration of citizen to 1.4 and I need to load Seaside 30 When I use the MetacelloRepository I get isTranscriptStream question because 1.4 does not have TranscriptStream Pier for Pier I have a problem since it reference to ImageSegments. Did any of you produce a correct configuration for Pharo1.4? Stef
