When compiling HYPHYMPI with 'bash build.sh MPI' from the HYPHY folder (created when running 'bash buildFromSVN.sh' without errors), I've got the following error:

I've got installed libmpich, but it seems it cannot be found by the script. Do I must tell it the location of libmpich? How?

Thanks in advance for your help, and keep on the good work...

I've changed gcc to mpicc and g++ to mpiCC (mpic-- is a synonym for mpiCC provided  for  filenames that do not support case-sensitive filenames), but now I have the following error:

(... error follows with many lines)

Any help?
