What, pray tell, are you talking about?
There are 3 paths searched:
* LD_LIBRARY_PATH and the executable's rpath
* the module's rpath
* the default path (/usr/lib,/lib)
All of these are part of ELF.
The rpath does not give you a path for each library/module; it gives
you a global search path for all of them.
