It only affects the binaries produced when using the option.
Packages/binaries can be built by any user, -R doesn't require
root privileges.

Using -rpath/-R is the norm for Solaris packages.  Samba
already is built with knowledge of where it is installed
and where its lib, data, var, etc directories reside.

What is _not_ the norm, is having to set LD_LIBRARY_PATH in
order for your applications to work.  Take a look at all
the packages at sunfreeware.com - they are all built for
/usr/local and, at least from hundred or so packages I've
installed from there, none require LD_LIBRARY_PATH to work
when their libraries are in /usr/local/lib.
