Is ifort in your PATH?
If not, the OpenMPI configure script will use any fortran compiler it finds first, which may be gfortran.
You need to run the Intel compiler startup script before you run the OpenMPI configure.
The easy thing to do is to source the Intel script inside your .profile/.bashrc or .[t]cshrc file.
I hope this helps,
