----------------------------+--------------------
 We're finding vtk @8.2.0_0 +python38 +qt5 +openmpi fails to build from
 source, for macOS versions 10.13--10.15.  Logfile enclosed, but here's
 what looks like the punchline:

 {{{
 macports.org_macports_release_tarballs_ports_graphics_vtk/vtk/work/VTK-8.2.0/Wrapping/PythonCore/PyVTKMethodDescriptor.cxx:189:3:
 error: cannot initialize a member subobject of type 'Py_ssize_t' (aka
 'long') with an rvalue of type 'nullptr_t'
 }}}

 .... plus an exactly similar type-conflict error lower down for
 `PyVTKReference.cxx` in the same directory.  This may or may not be
 related to [[ticket:60367]], qv.

 For completeness, the system info for the 10.14 build is:

 === MacPorts Version: 2.6.2 ===
 === macOS 10.14.6 ===
  * '''Build''': 18G2022
 === Xcode 10.3 ===
  * '''Xcode''': Build version 10G8
  * '''clang''': Apple LLVM version 10.0.1 (clang-1001.0.46.4)

 Hope this helps.  Do please let me know if there's further information you
 need.  Thanks in advance.
