I guess proj6 needs installing in gdal/scripts/vagrant/gdal.sh?

Operating system

Vagrant (Ubuntu 14.04/64bit)

GDAL version and provenance

master @ 4ee1c99

[miurahr]

I know GDAL 2.4.0 now include a [RFC73[(https://github.com//pull/1185): Integration of PROJ6 for WKT2 and now requires proj6 but Vagrant scripts have been with proj4, which is provided by ubuntugis project and my PPA for mingw compilation.

It is a big changes in dependencies and we may need to update many of packages based on proj6. How can we provide proj6?

Now proj project has an option to RENAME_SYMBOLS in git HEAD, that is used in Travis-CI scripts. Do we do same way, compiling proj with it, on Vagrant?

I'd suggest so. Recompiling all other dependencies against PROJ master would be unpractical
