AbstractLauncher was removed in: http://code.google.com/p/pharo/issues/detail?id=4002

Cog has a subclass from AbstractLauncher called CommandLineLauncher, hence, it cannot be loaded anymore

CommandLineLauncher has no class comment and no sender. So I have no idea what it does, nor if it can be removed from cog, nor how to solve this problem in Pharo.

Cheers
