Another example with KernSmooth:

   Error in linbin(x, gpoints, truncate) : object 'F_linbin' not found

Maybe this part of NEWS is what matters:

    * Packages which register native routines for .C or .Fortran need
      to be re-installed for this version (unless installed with
      R-devel SVN revision r72375 or later).

KernSmooth surely has .Fortran. Your spatial example had VR_frset failing,
and that too is called by the old .C.

A counter-example is eg my RcppEigen package -- I can load it and run
example(fastLm) just fine as that uses .Call rather than .C or .Fortran.

I think you are

 -- correct in that we need rebuilds
 -- but only for packages using .C and .Fortran calls to compiled

This may be a use case for r-api-4. Or not as it doesn't break _all_ packages
so I am not sure we should force _all_ packages to be rebuilt.

Can we not find the ones that use .C and .Fortran ?
