    9 I believe this occurs due to  a race condition in some build attempts for clang. Marcus disabled parallel_building one time to get past this -- but as it only happens to me 1 / 100 times  I build clang, and because building clang-12 without parallel building takes about 1.2 years, I re-enabled it again.

    13 If it really bugs you, you can disable parallel building in your clang Portfile.

    15 If it happens a lot, on the buildbots and elsewhere, and there is no choice left but to disable parallel_buildling, so be it, we'll disable it and it can take 1.2 years to build clang.
