In my experience, -rpath is a big PITA. For example, Red Hat used to ship a
libc5 CDE package that was linked -rpath /usr/X11R6/lib. In that time,
Debian's X was already libc6, and libc5 versions of the X libraries were in
/usr/lib/libc5-compat. This directory was in /etc/ld.so.conf, and the
dynamic loader was smart enough to know which library to use, /except/ when
-rpath was used. The result was that a libc5 binary, compiled for libc5 X
libraris, got loaded against libc6 X libraries, and segfaulted.
Now if -rpath's semantics were changed to it adding _to the end_ of the
dynamic loader's directory search path, it might actually be useful.
