Hello Harald,
please see:
http://www.open-mpi.org/faq/?category=mpi-apps#why-no-rpath
One possibility with Your existing installation is to circumvent a libmpi*
being used from the standard system library directories: just adapt Your
mpi*-wrapper-data.txt files in
/home/Computacional/harald/aplic/openmpi/1.2/share/openmpi
Instead of:
libs=-lmpi
set it to:
libs=/home/Computacional/harald/aplic/openmpi/1.2/lib/libmpi.a
Of course, You may play with -rpath in conjunction with
--with-wrapper-ldflags.
More info on this in:
http://www.open-mpi.org/faq/?category=mpi-apps#override-wrappers-after-v1.0
Hope this helps,
Rainer
