I did this because it allows 'default' (which comes into play when no gemsets are selected), to provide rake and bundler support to non-gemset defined executions, and allows the global gemset to have bundler available to all gemsets, while leaving rake to be installed per gemset which eliminates any and all potential versioning issues for rake.
