[R-pkg-team] Bug#979026: r-cran-rgdal: autopkgtest failure with PROJ 7.2.1

[Bas Couwenberg]

Source: r-cran-rgdal
Version: 1.5-18+dfsg-1
Severity: serious
Tags: upstream fixed-upstream
Justification: makes the package in question unusable or mostly so

Dear Maintainer,

The autopkgtest of your package fail with PROJ 7.2.1:

 Error: isTRUE(all.equal(a, matrix(c(-5.917698, -1.87195), ncol = 2),  .... is not TRUE
 Execution halted
 autopkgtest [23:01:36]: test run-unit-test: -----------------------]
 autopkgtest [23:01:36]: test run-unit-test:  - - - - - - - - - - results - - - - - - - - - -
 run-unit-test        FAIL non-zero exit status 1

This appears to be an issue with how upstream uses PROJ incorrectly,
as discussed on the PROJ list:

 https://lists.osgeo.org/pipermail/proj/2020-December/010014.html

Upstream doesn't appear to have a public VCS, so it's unclear if the fix
posted on the PROJ list can be easily turned into a patch for the Debian
package.

Kind Regards,

Bas
