Sorry, I don't support Power PC machines on ports maintained by me any more. I will apply patches to fix this if you can provide them, but not invest time to develop them myself.

Feel free to open a pull request.

The unavailable library functions have all __attribute__((unavailable)) set from pre-compiler.

[ballapete (Peter "Pete" Dyballa)]

It builds with configure.compiler=macports-gcc-7.
