--------------------+-----------------------
 The following files in the Python 3.10 build are not respecting the
 `MACOSX_DEPLOYMENT_TARGET`, similar to #67899 for `libstemmer`.

 As a reminder (if it's helpful) this was the fix for `libstemmer`:
 https://github.com/macports/macports-
 ports/commit/6d75c22ebad1cf495e688fba8cbc4db9266d6286.

 This affects the deployment build of GIMP.

 I would expect other Python versions to have the same issue.

 I would gladly create a PR but I'm not really sure how I'd go about it.

 This is the (snipped) output of `otool -l` for one of the `.so`s, but they
 are all the same:
