rgdal install fails (following GDAL building from source)

Dear all,

I'm using the (excellent) rgdal package for a while now, but following
the build from source of the last GDAL stable release, I can not
reinstall it.

When I'm asking for install.packages("rgdal"), I got the following error:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared library '/usr/lib64/R/library/rgdal/libs/rgdal.so':
  libgdal.so.1: cannot open shared object file: No such file or directory

From some internet search, I understand that it is possibly due to a

change in where GDAL has been installed, but I've been unsuccessful to
fix that so far.

Thanks for any hints.

Here is my config:
