Indeed, and it's quite impossible in the cases that are causing us
problems because the shared library in question is distributed in a
jarfile and extracted at runtime.  Setting RPATH is the only way to
get it to work, I think.  However, I note that on Linux use of
DT_RPATH is deprecated.  DT_RUNPATH, which doesn't override the use of
LD_LIBRARY_PATH, is better.
