You mean rewriting the RPATH on a produced ELF binary?
That's not practically possible.
1) The binary has to be built "unoptimized" to ensure the rpath string 
suffix isn't used by another symbol.
2) The new RPATH has to be shorter or the same length as the old RPATH
3) You need a tool to rewrite RPATHS - is far as I know Solaris and 
maybe Linux are the only ones that have it, and Solaris required a 
change in their linker (Solaris has an addition 200 characters than can 
be used for longer RPATH than original and needs a special symbol to 
track how many are left)

None of the BSDs as far as I know have the ability to rewrite RPATH in a 
guaranteed way although I have been trying to figure out the best way to 
modify gold linker to support rewriting RPATHS with longer versions for 
DragonFly.
