Found the following significant warnings:

See ‘/home/hornik/tmp/R.check/r-devel-gcc/Work/PKGS/enviPick.Rcheck/00install.out’ for details.
File ‘enviPick/libs/enviPick.so’:
  Found no calls to: ‘R_registerRoutines’, ‘R_useDynamicSymbols’

It is good practice to register native routines and to disable symbol
search.
