Hi,

I need to use OSSubprocess in a project with Moose 6. I just tried to load it in a new Moose 6 image but that's doesn't work. By the way, OSSubprocess works fine in the latest Pharo 5 image. 

Please find below the lats lines of Pharo error log:

By the way, OSSubprocess works fine in the latest Pharo 5 image. 

Someone has an idea ?
