 This appears to be happening when building a bundled copy of libxml2.

 Here is the vtk bug report:

 https://gitlab.kitware.com/vtk/vtk/-/issues/19530

 And the libxml2 bug report:

 https://gitlab.gnome.org/GNOME/libxml2/-/issues/820

 I'll apply the fix to the libxml2 port. Maybe vtk can then use MacPorts
 libxml2 to avoid the need to build its own?
