Intermittent pbulk build fail of editors/vim-share

["J. Lewis Muir" <jlmuir%imca-cat.org@localhost>]

Hello!

My pbulk build on Darwin (macOS Sierra (10.12.1)) of editors/vim-share
from pkgsrc-2016Q3 failed in the build phase.  However, I ran bulkbuild
again, and this time it built the package successfully.  When it failed,
the errors from build.log were as follows (more context from the log is
at the end of this email):

I haven't tried to see how reproducible this is, but my guess is that
it's probably going to be tough to reproduce and hence tough to track
down.  But, I thought I'd ask just in case.  Does anyone know what went
wrong and how to fix it?

Thanks!

Lewis
