yep, some recent changes to the build farm and makefile broke things
pretty badly. A patch I've just put in
(1b09e36f0bc1942a5156715db21aed1ad403800e) tries to recover some of
the errors, but I'm not sure it wll catch them all.

we need to work on fixing these problems. See the above patch for a
start on this. If we still hit failures that report as passes, we'll
need to dig deeper.
