 The following patch fixes it, but it's not clear how to proceed. It
 looks like archivers/pax was last updated from base in about 2008, and
 while it should be updated that's going to be a big job and probably
 break a bunch of bootstraps. But until that's done, changing files/
 is undesirable. But on the third hand, I don't think it's safe to add
 patches to bootstrap packages either, and that's the only other
 reasonable alternative.
