Comment (by herbygillot):

 > There's a simple solution: Create a 2nd port, cargo-devel, and update
 that first. We use that practice extensively elsewhere, and that solves
 this issue once-and-for-all.

 Fair point.  I'm trying to get a Sierra environment running in a VM on an
 Intel Mac locally, but it's been difficult finding an installer that
 works.  Any pointers?
