That's exactly right; then you just pick those up and drop them into
the package, and they come out in the expected full path locations on
the other end. (So the package "depends" on the X11R6
installation. That's fine...) You *want* to install things where
people will find them after all, and that means X programs go in
/usr/X11R6/bin.
