Maybe I should add that my Intel C++ and Fortran compilers are
different versions. C++ is 12.0.2 and Fortran is 13.0.2. Could that
be an issue? Also, when I check for the location of ifort, it seems
to be in usr/bin - which is different than the C compiler (even
though I have folders /opt/intel/composer_xe_2013 and
/opt/intel/composer_xe_2013.3.171 etc.). And I have tried /source
/opt/intel/bin/ifortvars.sh intel64/ too.

I am not a computer whizz so I hope I can explain what I did properly:
1) In bash, I did /source /opt/intel/bin/compilervars.sh intel64/
and then /echo PATH/ showed:
//opt/intel/composerxe-2011.2.142/bin/intel64:/opt/intel/composerxe-2011.2.142/mpirt/bin/intel64:/opt/intel/composerxe-2011.2.142/bin:/Library/Frameworks/EPD64.framework/Versions/Current/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:.:/Library/Frameworks/EPD64.framework/Versions/Current/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin/

2)/which icc /and /which icpc /showed:
//opt/intel/composerxe-2011.2.142/bin/intel64/icc/
and
//opt/intel/composerxe-2011.2.142/bin/intel64/icpc/
/
/
So that all seems okay to me. Still when I do
/./configure CC=icc CXX=icpc F77=ifort FC=ifort
--prefix=/opt/openmpi-1.6.4/
from the folder in which the extracted OpenMPI files sit, I get

You do need to examine config.log and show it to us if you don't
understand it.
Attempting to use the older C compiler and libraries to link .o files
made by the newer Fortran is likely to fail.
If you wish to attempt this, assuming the Intel compilers are
installed in default directories, I would suggest you source the
environment setting for the older compiler, then the newer one, so
that the newer libraries will be found first and the older ones used
only when they aren't duplicated by the newer ones.
You also need the 64-bit g++ active.
It's probably unnecessary to use icpc at all when building OpenMPI. icpc
is compatible with gcc/g++ built objects,
