According to the config.log, Espresso finds a MPI implementation 
in /opt/hpmpi, which seems to be some HP-specific implementation. Espresso 
then tries to use this library in the standard way, which however may not 
work with this library. It tries to start using mpirun -np 4 <binary, i.e. 
obj-xxx/Espresso_bin> <scriptname> <script parameters>. Please check with the 
documentation of your MPI library whether this is the correct call, or 
whether you need other parameters.
