   When I update.packages() I'm told that the attempt ended with a non-zero error message:

Warning message:

   The update to version 1.3-3 last May worked. What might be the reason the
upgrade to 1.3-4 fails?

   R produces contradictory messages:

configure: C++11 support available
configure: rgdal: 1.3-4
   ...
checking for gdal-config... /usr/bin/gdal-config
checking gdal-config usability... yes
configure: GDAL: 2.3.0
checking C++11 support for GDAL >= 2.3.0... yes
checking GDAL version >= 1.11.4... yes

   Looks OK, yes? But, immediately following is this:

In file included from /usr/include/gdal.h:45:0,
                  from gdal_test.cc:1:
/usr/include/cpl_port.h:187:6: error: #error Must have C++11 or newer.
  #    error Must have C++11 or newer.
       ^
   ...
configure: Install failure: compilation and/or linkage problems.
configure: error: GDALAllRegister not found in libgdal.
ERROR: configuration failed for package ‘rgdal’
* removing ‘/usr/lib/R/library/rgdal’
* restoring previous ‘/usr/lib/R/library/rgdal’

  Yet configure found C++11 support for gdal and the version of the latter is
greater than 1.11.4.

TIA,
