The main reason for renaming for ORTE and OPAL libraries was to avoid
conflicts with others open source libraries (libopal is some kind of
communication library available on most of the linux distributions).
In same time, our wrapper compilers have been modified to take these
changes into account. Usually, from a user perspective (where a user
is supposed to use mpicc to compile MPI applications) there should be
no difference.

Right, libopal and liborte have been renamed to libopen-pal
respectively libopen-rte. Creating backward compatibility links to
the renamed libraries is just a way to ask for troubles. Having 2
libopal.so in the system libraries doing completely different things
will definitively not help the end users. Moreover, applications
compiled with Open MPI 1.1.4 will not work without a recompilation
with any ulterior (such as the 1.2) version of Open MPI.
