If the latter, the fix should be in base, not in individual ports.

The latter. MacPorts is in almost all cases choosing inappropriate alternatives for PowerPC.

On PPC, the compiler should default to gcc42 (whichever flavour - there are a couple of different variants of that - apple-gcc42 or gcc42 are for all intents and purposes the same compiler for our purposes). If  *gcc42 is blacklisted, MacPorts should then go to gcc6.

There should be no other choices unless something is explicitly whitelisted (like gcc5 for pdftk).

If you know how to make this happen, that would be great!

[aside — that actually won’t fix quite a few ports, which just blacklist *gcc* — that has to be undone on PPC all the time, as it is inappropriate for PPC to do that.]
