proj4 is missing datum grids
As of version 5.0.0 PROJ expects certain datum grids to be present in
the proj directory. Otherwise, PROJ performs coordinate transformations
in certain cases without applying the correct grid shift. This leads
to incorrect coordinates after transformation.
The datum grids can be obtained from
and should probably be added to the proj package.
