Comment (by ryandesign):

 Replying to [comment:53 michaelld]:
 > I've attached my boost directory with the updates from Mark for Python3
 and MPI as well  as 1.65.1. All patches apply cleanly for the various
 variants. All of my boost-dependent ports require rebuilding to run, as is
 usual with updated boost (sigh).

 So can I commit this (along with revbumping all ports linking with boost,
 of course) or is something else still needed?
