In the boldface line it refers to an openmpi-2.0.4 installation. It appears that the 3.0 build is trying to use libraires or includes from the 2.04 install instead of the 3.0 build. Can you carefully define your PATH and LD_LIBRARY_PATH (or whatever linux calls it) to prevent the 3.0 build from accessing the 2.04 build libraries and includes (modules is another way to accomplish this).
