But that is contrary to the usual practice, fixed so that stuff built and 
installed locally, with identical names to the distro's /usr/bin 
contents, is found first in /usr/local/bin and the newer version is 
used.

That "usual practice" is going to be a very high hill to climb. I 
personally would never consider it as a solution to this p2 vs p3 
problem.
