I don't think this a good idea in general: when users are bit by this they can deal with the error and delete the package by hand. If we do this automatically, however, reloading the same version twice will cause all methods that were added later to be forgotten, as well as additions to *CENTRAL-REGISTRY*, etc. If something along the lines is put it, I would suggest that TRT is to signal an error and offer restarts to either delete the package or continue blindly.
