FYI, from the new gABI:
-----
A fourth search facility, the dynamic array tag DT_RPATH, has been
moved to level 2 in the ABI. It provides a colon-separated list of
directories to search. Directories specified by DT_RPATH are searched
before directories specified by LD_LIBRARY_PATH.
If both DT_RPATH and DT_RUNPATH entries appear in a single object's
dynamic array, the dynamic linker processes only the DT_RUNPATH entry.
