> use -rpath /usr/lib for their programs. Just to make it clear, since I don't think this has come up yet, /usr/lib isn't the only problem -- /usr/X11R6/lib is as well (or was, at some point; I haven't looked at the upstream XFree86 Imake configuration recently, but it did use --rpath at one point in the libc5 days.) Thus the substitution approach needs to be a slightly more general mapping.
