That error looks like it's coming when building with the system compiler, not the compiler under test, interestingly enough. When it tries to build with clang, we get a slew of errors like:

I'm tending to agree that there's something bogus on the tester. Who owns that box that we can ping to check it out?

Also, it might be worthwhile to change its configuration to run with TEST=simple rather than TEST=nightly. That would speed up the cycle time quite a lot.
