Besides library information, you also have to pass the flags for the 
compiler to find MPI headers/modules both for C and Fortran, perhaps this 
is what causing problems.  You can check why the compilation failed in the 
config.log file.

In any case, with mpich is better to specify as compilers the wrapper 
scripts (mpicc and mpif90) instead of passing the flags directly.

Cheers,
