You need to set your LD_LIBRARY_PATH to point to where you installed openmpi.

Hi,
I am trying to get openmpi-1.4.3 to run but am having trouble.
It is run using SUSE-11.3 with Intel XE-2011 Composer C and Fortran
compilers. The compilers installed without problems. The openmpi
file was downloaded and unzipped and untarred. The ./configure
command was run and it was found to be necessary to set CC=gcc and
CXX=g++. The fortran F77 and F90 were set to ifort. The --prefix was
set to /usr. The program appeared to compile properly but none of the
examples given would not compile. The error messages are shown below:
linux-q2bz:/home/amosleffler/Downloads/openmpi-1.4.3/examples # mpicc
hello_c.c =o hello_c
mpicc: error while loading shared libraries: libopen-pal.so.0: cannot
open shared object file: No such file or directory
linux-q2bz:/home/amosleffler/Downloads/openmpi-1.4.3/examples # mpiCC
hello_cxx.cc -o hello_cxx
mpiCC: error while loading shared libraries: libopen-pal.so.0: cannot
open shared object file: No such file or directory
linux-q2bz:/home/amosleffler/Downloads/openmpi-1.4.3/examples # mpif77
hello_f77.f -o hello_f77
mpif77: error while loading shared libraries: libopen-pal.so.0: cannot

linux-q2bz:/home/amosleffler/Downloads/openmpi-1.4.3/examples # mpif90

mpif90: error while loading shared libraries: libopen-pal.so.0: cannot
open shared object file: No such file or directory
linux-q2bz:/home/amosleffler/Downloads/openmpi-1.4.3/examples
It is evident that the same error is present in all attempts to
compile but I don't know why it is absent. Any help would be much
appreciated.

These FAQ detail what David and Ralph said:

You can prepend or append (don't overwrite)
the OpenMPI library directory to your current LD_LIBRARY_PATH,
so as to keep he Intel ifort library path there also.
My two cents,
