Perhaps you forgot to make the Intel compilers active in your configure
session. Normally this would be done by command such as
source /opt/intel/composer_xe_2013/bin/ intel64

In such a case, if you would examine the configure log, you would expect
to see a failed attempt to reach ifort, falling back to your gfortran.

On the C and C++ side, the MPI libraries should be compatible between
gnu and Intel compilers, but the MPI Fortran library would not be
compatible between gfortran and ifort.
