right: some time ago I tried bootstrapping trunk on FreeBSD 14.0 myself,
which was a very rough journey unfortunately. I've filed a number of
PRs for the issues found. They should all be referenced in
PR target/112959 install.tex needs updates on FreeBSD
which is primarily a call for documention so the next unwary non-FreeBSD
developer won't run into all the same known issues again.
