It is obviously finding some trilinos libraries from somewhere otherwise it
wouldn't be running at all (unless it is using a different solver). What is
the path to the libraries that it is currently finding and what is the path
to the libraries that you want to use?

In general, trilinos needs it to be set. I am not sure whether that is
always true or when you have it installed in non-standard locations. Have
you installed it in a standard place? If you are on a cluster then maybe
not.
Is there a way I can explicitly set the locations of all the libraries

Never heard of RPATH.
