Comment (by ryandesign):

 Replying to [comment:2 jmroot]:
 > Seems to have built OK on the buildbot.]

 Yes, py39-libxml2 succeeded on the buildbot when it was last updated three
 weeks ago. I thought something might have changed since then.

 > I take it this is a local build.

 Yes, on macOS 12 x86_64.

 > Do you have py39-importlib-metadata installed?

 Yes, but I am using trace mode and I should have added that this appears:

 {{{
 Warning: The following existing files were hidden from the build system by
 trace mode:
 /opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9
 /site-packages/importlib_metadata/__init__.py
   /private/var/select/sh
 }}}

 When not using trace mode, the build (of either py39-libxml2 or
 py39-setuptools) succeeds.
