The new https://github.com/python/performance benchmark suite has a very different design than the old https://hg.python.org/benchmarks benchmark suite:

* it now only runs benchmarks in a virtual environment
* dependencies are installed in the venv by pip
* there is a "run" command which now accepts a --python=PYTHON option to choose the Python binary (and so the tested Python version)

There is no more such thing as ported_lib().

Can I now close this issue as outdated, or do you consider that performance still has this issue?
