Fails to build from scratch on some OS X Mojave machines. I think the issue is that on the affected machine, there is no directory /usr/include. What happens is that due to a configure check (from #26286), zlib is not built, but then Python cannot find zlib and so builds without zlib support. Without zlib support, pip won't build. Previous versions of Sage, at least as of 8.5.beta4, build on this machine, so I think #26286 is the issue. (It's perhaps a rare case, so no blame to the authors and reviewers there.)
I've opened up https://trac.sagemath.org/ticket/26899 for this.
