[R-SIG-Mac] Rebuild binaries when a LinkingTo dependency changes

[Kirill Müller]

Hi


The TMB package has Matrix in its LinkingTo dependencies. In a clean 
package library, I see behavior posted below.

Should the TMB package have been rebuilt when a new version of the 
Matrix package was pushed? More general, should we rebuild all reverse 
LinkingTo dependencies of a package that gets an update on CRAN? This 
will mean a lot of package rebuilds with Rcpp, but also a lot less 
frustration down the road. Thanks!


Best regards

Kirill
