This was fixed by commenting out the .onLoad and .onUnload functions in `zzz.R (thanks to Kurt Hornik for pointing this out).

background for future reference (or any Google search that might run into same issue)
The underlying issue was with the RegisterCallable functions not being in the right place in the RcppExports file. Before suggesting the onload/onunload fix, Kurt Hornik pointed out that moving the R_RegisterCCallable function into the R_init_LambertW fixes the insallation of package problems:

RcppExport void R_init_LambertW(DllInfo *dll) {
    R_registerRoutines(dll, NULL, CallEntries, NULL, NULL);
    R_useDynamicSymbols(dll, FALSE);
    R_RegisterCCallable("LambertW", "_LambertW_W_Cpp", (DL_FUNC)_LambertW_W_Cpp_try);
    R_RegisterCCallable("LambertW", "_LambertW_W_delta_Cpp", (DL_FUNC)_LambertW_W_delta_Cpp_try);
    R_RegisterCCallable("LambertW", "_LambertW_W_delta_alpha_Cpp", (DL_FUNC)_LambertW_W_delta_alpha_Cpp_try);
    R_RegisterCCallable("LambertW", "_LambertW_W_gamma_Cpp", (DL_FUNC)_LambertW_W_gamma_Cpp_try);
    R_RegisterCCallable("LambertW", "_LambertW_RcppExport_validate", (DL_FUNC)_LambertW_RcppExport_validate);
}
  • commenting out
## # Register entry points for exported C++ functions
## methods::setLoadAction(function(ns) {
##     .Call('_LambertW_RcppExport_registerCCallable', PACKAGE = 'LambertW')
## })

While this fixed it too, it was a bit hacky since roxygenize / devtools:build overwrites the RccpExports.cppfile -- so the fix must be done by hand again. Commenting out onload/onunload works now automatically w/o having to modify files by hand.
