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

[Sven Van Caekenberghe]

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
