 On legacy hard- and software it may be hard to impossible to do so
 unfortunately, so I solved this issue for myself like this. I share my
 experience here to the benefit of anyone with the same issues. Hopefully
 someone might benefit from it, either by someone from MacPorts
 incorporating my solution, or by individual direct use by end users who
 prefer building rather than pulling binaries.

 Cheers
