#67471: sentencepiece @0.1.97: error: aligned deallocation function ... is only
available on macOS 10.14 or newer

------------------------+---------------------------
 sentencepiece @0.1.97 fails to build on Mac OS X 10.6:

 https://build.macports.org/builders/ports-10.6_x86_64-builder/builds/155618/steps
 /install-port/logs/stdio
 {{{
 src/../third_party/protobuf-lite/google/protobuf/stubs/mutex.h:160:5:
 error: aligned deallocation function of type 'void (void *,
 std::align_val_t) noexcept' is only available on macOS 10.14 or newer
     delete static_cast<T*>(value);
     ^
 }}}
 I don't understand the message since the port builds fine on OS X 10.8 and
 later.

 Does sentencepiece need to use its bundled copy of protobuf-lite? Could it
 use one of the separate protobuf ports already in MacPorts? Might that
 solve the problem?
