py-pyarrow destroot failure on ppc: whl is not a supported wheel on this platform

[barracuda156]

I am getting a silly error at destroot:

Executing:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_apache-arrow/py311-pyarrow/work/arrow-16.1.0/python" && pip-3.11 install --ignore-installed --no-cache-dir --no-dependencies --root /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_apache-arrow/py311-pyarrow/work/destroot /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_apache-arrow/py311-pyarrow/work/arrow-16.1.0/python/dist/pyarrow-16.1.0-cp311-cp311-macosx_10_6_ppc.whl

How to fix it? pip in the current version seems to be aware that ppc still existed in 10.6.
