... the sympthom being an error while #include <omp.h> in r-release-macos-x86_64, we identified the problem as a lack of appropriate linkage of OpenMP. 
  
Solution: 
  1.- the header inclusion and all usages of #pragma directives were enclosed in conditional structures
#ifdef _OPENMP 
   ...
#endif 
  
   2. `$(SHLIB_OPENMP_CFLAGS)` was added to PKG_CFLAGS and PKG_LIBS fields in Makevars files
  
  NOTE: we do not have access to any MacOS machine to test that our solution is effective. Our apologies if this is not working!
