Hi, 

while trying to build the ET on the Marenostrum cluster (from the Barcelona Supercomputing Center) I obtain the following error: 

Configuring with flesh MPI  Warning: use of flesh MPI via MPI option is deprecated and should be replaced with the thorn ExternalLibraries/MPI and its MPI_DIR option  MPI selected, but no known MPI method - what is "impi" ?

Error reconfiguring sim_cx-config make: *** [Makefile:732: sim_cx-config] Error 2

The MPI thorn is on the thornlist and can be found on the repos folder as an external library. On the other hand, members of my group have already installed the Toolkit on this cluster, and I am using the same configuration file as they are, so I am unsure what the problem might be. 

I am still quite new to this kind of task, so I would appreciate any help. Thanks!
