Yes, you need to do the latter, or (if the headers are for standard 
libraries that users should obtain elsewhere) add a configure script so 
that R can find them on a user's system, and note the requirement in the 
DESCRIPTION file SystemRequirements field.  It's better if the .tar.gz 
file is self-contained.
