I think I might have caught one. On High Sierra I am rebuilding and
llvm11 is being pulled in as a dependency (didn't have it previously)
and it fails to build with existing clang-9 due to strange linker

xar has definitely already been rev bumped. I don't know why yours has
not been built against the new libxml2, as the llvm ports do depend on
xar which will cause it to be upgraded first.
