Hmmm, I think someone needs to rethink the system set then.  After all,
portage does not work well without python.  It should keep a binary copy
but it should also warn you if you are typing without your thinking cap on.

Anyone else think this is a bug?  Or should be thought out again as to
being included is system set?
