You have to set LD_LIBRARY_PATH when _running_, not when compiling

Good point.
Under LINUX, in order to embed the library path into the executable, you
have to

1) either use the -rpath option to the linker

2) set LD_RUN_PATH when linking (note the difference: LD_RUN_PATH

is evaluated by the linker, LD_LIBRARY_PATH by the runtime linker,

i.e. when executing the linked application)

Note that setting the SHRLIB_SEARCH_DIRS variable adds the necessary
-rpath options. It has only been implemented on Linux though - we should
probably do the same thing on all Unix class OSs, but I believe Linux is
currently the only OS where we build and use shared libraries by default.
I don't like having a manual setting, but some sites need to be able to
use different paths at build time and run-time.
