I think the idea is that you want to specify the path in the config
file, after the app has already started. I don't think you can modify
the environment variable after the app has started, and even if you can,
it seems simpler to just do it in our code and specify the exact path
rather than having it poke around in whatever LD_LIBRARY_PATH is set to.
