Mac High Sierra users will need to debug installation of PROJ.4 5.0.0 from

work with proj.4 4.9.3, I hope?
Yes, backward compatibility continues to be important, and Windows and OSX
CRAN binaries are < 5.0.0. However, in a year or so, we may be ready to
switch, and then no further maintenance will be done for the < 5.0.*
code. It will entail moving away from rgdal::spTransform() and
rgdal::project() as they are now structured, and rather using a fully
qualified pipeline inside PROJ, without first transforming to WGS84 then
on to the target representation.
