written in fortran with it? for example the 'pi' example referred

configure only tests whether a parallel compiler wrapper is
installed and whether it can compile, link and run a simple,
non-parallel executable. it assumes that it is installed
correctly for parallel codes if it works on a minimal serial
test. otherwise, you have much bigger problems than getting

as i was already noting in my previous response, this is
not a problem of OpenMPI by itself, but a problem of an
incorrect installation. so either you must have a messed
up the installation of openmpi, or you have an incompatible
or bogus mpif.h file somewhere where it is picked up by the
mpi compiler wrapper. Both, OpenMPI and LAM/MPI work
fine with espresso, and since you get the same error message
with both packages, the latter seems more likely.

that only confirms that the problem is the MPI installation.

the simplest workaround is always to hire somebody, who knows
about these things. the symptoms you describe are very obvious
to check and sort out, so there should be enough people somewhere
close to where you are located to have a look at your machine(s),
detect what is messed up and sort it out.
as discussed many times with people having compilation problems,
these are very difficult to sort out remotely, particularly if
there are indications of an inconsistent installation.
it is obviously not a defect of quantum espresso by itself, or
else you would not be the only person reporting it. there are
a lot of people using either openmpi or lam/mpi.
depending on how large your deployment is, you could also consider
wiping the machine and installing a clean distribution. e.g. fedora has
been working for me out of the box (it has suitable packages for
openmpi, gfortran, atlas as part of the distribution) since version 6,
i.e. since two years ago. i'd assume that others like debian 5, ubuntu
08XX or RHEL/CentOS 5.x work just as well.
it only gets nasty, if you have to include support for a specific
high-speed interconnect or include program launching through a
specific batch system, both of which would require a custom compile.
adding support for non-native compilers to openmpi can be done without
a recompile, all you need is a suitable symlink to opal_wrapper (or
opal_wrapper-64, or /etc/alternatives/mpicc in some distros) and
