I'm not the expert on these problems, but as nobody else has
replied:

My experience is that both Rcpp and BH need  "often" to be
re-installed if your system updates in some way.
IIUC, 'LinkingTo:'  is actually a misnomer (as e.g. the Rcpp maintainer
      		     has known and told us about often enough),
here, because it's more a "including C++ header templates from"

So, I'd re-install first  Rcpp, then BH,  and then "your"
package.

Please let us (= the audience) know if that helped.

Best,
Martin
