    # The exception is libjson-rpc-cpp, which we have to build from source for
    # reliable results.   The only binaries available for this package are those
    # we made ourselves against the (now very old) v0.4.2 release, which are unreliable,
    # so instead we build the latest release label (v0.6.0) from source, which works just
    # fine.   We should update our PPA.

    # Hmm.   Arachnid is still getting this issue on OS X, which already has v0.6.0, so
    # it isn't as simple as just updating all our builds to that version, though that is
    # sufficient for us to get CircleCI and TravisCI working.   We still haven't got to
    # the bottom of this issue, and are going to need to debug it in some scenario where
    # we can reproduce it 100%, which MIGHT end up being within our automation here, but
    # against a build-from-source-with-extra-printfs() of v0.4.2.

    # in the code.
