Did you copy OMPI to the same directory tree that you built it?

OMPI hard-codes some directory names when it builds, and it expects to find that directory structure when it runs. If you build OMPI with a --prefix of /foo, but then move it to /bar, various things may not work (like finding help messages, etc.) unless you set the OMPI/OPAL environment variables that tell OMPI where the files are actually located.
