Dovecot will not compile (Sonoma 14.7.5, MacPorts 2.10.7, Intel). cstddef.h not found.

My understanding is that reclaim does only remove unused stuff.

At some point I have many versions of python on my systems, and not only that different systems had ports that were using different versions of supporting ports (like python 3.9 versus 3.10). As these were ‘used’ they are not removed by reclaim.

So, the only way to get a fully clean (no ports installed at all) MacPorts is

sudo port -f uninstall installed
sudo port -N reclaim

After which you can reinstall your ports. A port that used to rely on python 3.9 gets freshly configured to use 3.10, where simply updating the port keeps the old choice in place.
