[R-sig-Geo] rgdal with R > 3.5.x and GDAL > 2.3.x on macOS

[Patrick Schratz]

Hi Roger,

thanks for taking the time. To defend myself, I do not use macOS on a daily base and just run it in a VM for some package testing.

This seems to be the problem. Using your configuration works!
I am aware of the small geospatial com on mac and that the osgeo4mac repo is not very stable. However I think there is a need for a short guide how to either use the kyngchaos frameworks or the osgeo4mac repo to have a stable geospatial toolset for R (starting with rgdal to sf and so on). Ideally for different R versions if major changes occured. A good place would be the README of rgdal if would be hosted on r-spatial on Github as most people would look there. As I saw in some issues, people sometimes think the cran/rgdal mirror is the place to go. But thats all just suggestions ;)
This little issue costed me at least 3h. Its really annyoing to have such issues on macOS from time to time (but ofc this is not your or anyone else fault).
Thanks again!!
Patrick
