[Pharo-project] DuplicatedVariableError: styler is already defined in PluggableTextMorph

When trying to do: Gofer new renggli: 'omnibrowser'; package: 'OmniBrowser'; package: 'OB-Standard'; package: 'OB-Morphic'; package: 'OB-Shout'; package: 'OB-Refactory'; package: 'OB-Regex'; package: 'OB-SUnitIntegration'; load (Part of the build scripts of LR's builder scripting package) I get the following error: DuplicatedVariableError: styler is already defined in PluggableTextMorph while loading the definitiion of OBPluggableTextMorphWithShout in PharoCore 1.2 #12294. I have seen some things flying around on the mailinglist related indirectly to this issue. Is there a solution ? Thx, Sven
