Yes, libtool can solve this problem!

If the libraries you are linking against are libtool libraries
(.la), and they are correctly installed, then libtool should be
automatically setting the runtime path appropriately.  That way,
the libraries will be picked up automatically from the nonstandard

Otherwise, you might consider linking your programs with the
-R/path/to/your/libraries option.

There should be no need to set LD_LIBRARY_PATH, although it can
work in a pinch.
