I do remember having similar problems, and although not sure, maybe the 
issue came from mixing different compilers.

Is maybe configure picking your mpif90 compiler (which uses intel) as 
the fortran parallel compiler, and gfortran as the serial one? If so, 
you might want to use the FC env variable and point it to the intel 
compiler manually.

Just guessing anyway...
