 > Not that it is relevant, but the build uses a macports provided clang
 version to build. Building gcc11 with gcc itself is not yet supported
 (although now gcc10 and newer support using libc++ as the c++ runtime
 doing so is more viable).

 In fact building `gcc11` with `gcc` itself works perfectly fine (no
 circular dependencies, no trickery), I have built in multiple times across
 several systems. Portfile needs few fixes, and I know precisely which now.
 That gonna enable building on 10.5.8 for PPC. (There are additional
 complications with 10.6 PPC and 10.6.8 Rosetta: the first needs a custom
 patch, which I will have to provide as out-of-tree fix on Github; the
 second does not need any patches and is supported by the upstream, however
 Macports `gcc10-bootstrap` fails on Rosetta due to dependencies using
 wrong arch setting – perhaps fixable, but I do not have it done yet.)
