Hi Cristobal
Try using the --prefix option of mpiexec.
"man mpiexec" is your friend!
Alternatively, append the OpenMPI directories to your
PATH *and* LD_LIBRARY_PATH on your .bashrc/.csrhc file
See this FAQ:
http://www.open-mpi.org/faq/?category=running#adding-ompi-to-path
I hope it helps,

/opt/openmpi-1.4.2/ is shared through NFS.
master node did had an older openmpi version before installing 1.4.2,
but i removed them all with
sudo apt-get --purge remove libopenmpi1 libopenmpi-dev openmpi-bin
openmpi-dev openmpi-common
i checked for /usr/lib64/openmpi and for /usr/lib/openmpi and
deleted them.
however, when compiling again i keep getting this error,
something must be remaining from the older version of openmpi, but i
really dont know where that remaining could be.
any help, welcome
