If you must, put it in a shell script wrapper. And even then, any sub-processes
that you start will probably be lumbered with your LD_LIBRARY_PATH.

That sounds just like everyone putting their DLLs in c:\windows\system32.

* use RPATH (with $ORIGIN if necessary). This is THE decent and nice way of
doing it. The only restriction is for apps that need high security, but then the
horrors like LD_LIBRARY_PATH are in the same boat.
