--- Comment #7 from Kubilay Kocak <koobs@FreeBSD.org> ---
(In reply to Chris Hutchinson from comment #6)

Unless the symbols in question are only provided in 2.9.10_3, and the ports
require those symbols, then yes. 

However, this appears to be the likely result of a libxml2 shared library ABI
change, without a subsequent py-libxml2 (consumer) shared library update.

That can be caused by shared library version changes, without consumer ports
having their PORTREVISION bumped, or by modifying port options that change the
shared (libxml2) library ABI, without rebuilding consumer ports (py-libxml2) 

The last update to libxml2 was 21 Jun 2021 21:19:10, cc'ing maintainer in case
they're aware of possible consumer ports impacts for additional comment, but
this appears to be 'not a bug'.

Accordingly, closing as resolved given comment 6.

Don't hesitate to re-open the issue with additional detail and reproduction
steps if that is not the case, or additional changes are required
