There are two issues here:

First, the fact that the name of the library is libglobus_duroc... 
indicates that you are probably using the MPICH-G2 library.  For your 
platform, this is probably not the best choice.  You should use either the 
native Sun MPI implementation or a version of MPICH2 that supports sockets 
(or sockets and shared memory).

Second, this problem usually indicates that a shared library (things ending 
in .so.digits) is either not installed on one of the machines or the search 
path for shared libraries is not set appropriately on each system.  Make 
sure that any shared libraries for the MPI implementation are installed in 
the same place on each machine (either in a file system that all nodes 
mount or as identical copies on all systems).
