Failure to build webkit-gtk

[Paul Goyette <paul%whooppee.com@localhost>]

On a NetBSD-9.99.81 amd64 host (built just BEFORE the switch over to
gcc-10) with an initially empty sysutils/mksandbox, and my pkgsrc
was updated on 2021-04-23 at 17:43:13 UTC.  I'm trying to rebuild
www/webkit-gtk after having succcessfully built and installed all
dependencies, and I'm getting the following error message:

/tmp/pkgs/www/webkit-gtk/work.x86_64/webkitgtk-2.32.0/Source/JavaScriptCore/runtime/IntlSegmenter.cpp:128:77: error: 'ubrk_safeClone_69' was not declared in this scope; did you mean 'ucol_safeClone_69'?
  128 |     auto segmenter = std::unique_ptr<UBreakIterator, UBreakIteratorDeleter>(ubrk_safeClone(m_segmenter.get(), nullptr, nullptr, &status));
      |                                                                             ^~~~~~~~~~~~~~

There seem to be a number of additional errors, all complaining about
no declaration for ``ucol_safeClone_69''

Any clues?
