Every tutorial on gEDA should state up front: LIBRARY SYMBOLS ARE ONLY STARTING POINTS. COPY AND CUSTOMIZE THEM TO FIT *YOUR* DESIGN FLOW AS NEEDED. So, if you want to use separate power symbols, copy the library symbols to your project's symbol repository, and delete the net= attributes. That the symbol browser doesn't copy the symbol to a project repository by default (assuming that this is defined in gafrc) is a problem. It perpetuates the illusion that the library is universal to all flows, and that such a library is possible. On the other hand, ONCE YOU HAVE MADE THE PROJECT LOCAL COPY, Hierarchy->Down Symbol is very useful.
