Some questions about this result:

1.  Is it generally expected that snapshot tags should build on OSX?  I thought it would be more likely to build than HEAD.  Am I wrong?  Is it preferred to build HEAD for general use?
2.  Has this issue been fixed?  I cannot find a reference to "WARNING: Title underline too short" (which might be the failing error?  although the output continues for quite some time) on this list or on bugs.swift.org <http://bugs.swift.org/>, but presumably somebody has tried to build Swift at some point in the past few days
3.  Is there something wrong with my config?

Sorry for asking a "hurr durr how to build" question, but I am still getting oriented with the build system and initial searching did not turn up anything relevant to the Swift project specifically.
