Strange build failure

[Quentin Spencer <qspencer ieee org>]

I don't know what to make of the build logs at:
http://buildsys.fedoraproject.org/logs/fedora-development-extras/6430-octave-2.9.4-8.fc5/ppc/

build.log is empty, job.log says:

Job failed due to build errors!  Please see build logs.


and root.log ends with:

Total download size: 74 M
Cleaning up...
Done.

So, what just happened?
