That setting is local to the session, so it is lost when you restart 
RStudio.

Generally rebuilding packages happens in a spawned session, so even if 
you ran Sys.setlocale() in the session doing the building, it wouldn't 
make a difference.

As Serguei said, set the environment variable LANG before starting R. 
It might work if you set that env var within RStudio before building the 
package (since spawned sessions inherit env vars), but only for the 
messages printed during the build.
