The usual cause for this is that the shared library cannot be found at run time. Can you verify if /usr/local/lib is in your LD_LIBRARY_PATH on all nodes, and/or /usr/local/lib is in the normal run-time linker search paths?

Note that you might need to check this in a non-interactive rsh/ssh login -- the setups may be different than for interactive logins.

Also, can you verify that libmpi_f90.so.0 is in /usr/local/lib? You mentioned "the library with libmpi_f90" -- there should likely be one library and one or more sym links.
