At the end of the buildbot failed message these lines appear:

• • • error building product afw.
    • exit code = 1
    • log is in /lsst/home/lsstsw/build/afw/_build.log
    • last few lines:
      ::::: + echo '*** Failed unit tests.'
      ::::: *** Failed unit tests.

This is not true. As Robyn points out, the correct location of these files is implied by statements at the top of the message:

Failed Package Info at lsst-dev.ncsa.illinois.edu:/lsst/home/lsstsw/build/FailedLogs/328/
.......Log */_build.log

by which is meant

dev.ncsa.illinois.edu:/lsst/home/lsstsw/build/FailedLogs/328/afw/_build.log

It'd be nice if this were a little more explicit.
