You can avoid the "library confusion problem" by building 64 bit and 32 bit
version of openMPI in two different directories and then use mpi-selector
(on your head and compute nodes) to switch between the two.

Be careful with this one; you want to ensure that your local shell
doesn't expand $LD_LIBRARY_PATH and simply display the same value on
all nodes. It might be easiest to write a 2 line script and run that:
$ cat myscript
echo LD_LIB_PATH on `hostname` is: $LD_LIBRARY_PATH
$ chmod +x myscript
$ pdsh myscript
