see pkg_info(1), especially the -[rR] options & portupgrade(1) and
-[nrR] options.
also, be careful when you go un-installing by solely depending on the
the presence, or content of, +REQUIRED_BY, file as that file may be
missing or not properly updated... say if you install/deinstall/install
in a dependency port directory. sorry for that long "sentence".
