[R-sig-Geo] library rgdal 1.5-15 installation failed

[Roger Bivand]

A known problem for users of outdated PROJ and GDAL; work-around

install.packages("rgdal", repos="http://R-Forge.R-project.org")

until next release (submission when 
https://cran.r-project.org/web/checks/check_results_rgdal.html updates to 
1.5-15 for all platforms).

Error initially trapped by the Solaris platform in CRAN package checks, 
thanks to Brian Ripley for alerting me that I had omitted to check the 
package with outdated PROJ/GDAL before submission; error not trapped by 
the CRAN submission system because those platforms use recent PROJ/GDAL.

As package maintainer, I recommend (strongly) staying as close to current 
system requirements as possible, because those version fix often serious 
bugs and offer much enhanced processing. In the case of PROJ/GDAL, from 
PROJ >= 6 and GDAL >= 3, the data models and APIs change radically, and we 
cannot be sure that we can test for outdated versions (this happened in 
this case because of a rushed release to fix a different problem).

I believe that things should still avoid failing, but will be more and 
more outdated. The gate for outdated PROJ/GDAL has to be kept open for 
really bad choices (legacy OS versions without available builds of more 
recent versions of GDAL and PROJ). However, as in this case, it may not be 
possible to test for dozens of external system requirements combinations, 
including reverse dependency checks for almost 900 packages using rgdal 
and rgdal through raster. Revdeps run yesterday with the development 
version of rgdal and PROJ 5.2.0 / GDAL 2.2.4 show no remaining problems 
caused by rgdal.

Users are strongly encouraged to move to as recent PROJ and GDAL releases 
as possible; CRAN Windows binaries (and shortly OSX binaries) are fairly 
recent. A maintainer's life is rarely a happy one ...
