Comment (by raimue):

 This was not the first build failure for xorg-libXau, as the port failed
 to fetch before. But the log was also lost, probably both caused by a
 temporary network problem: https://travis-ci.org/macports/macports-
 ports/jobs/365900385#L945

 I noticed the `runner` is not using `mpbb list-subports`, but
 [https://github.com/macports/mpbot-
 github/blob/c68ab523c6c357239a48734aba8498a762e755ef/ci/portutil.go#L18
 some other method]. Therefore the list of ports to build is not sorted in
 dependency order. I am not sure if this could be the cause, but it should
 be fixed anyway.
