[Pw_forum] mpif90 compiler that uses ifort

Hello all;
I had a problem in installing QE 4.0.3 using Intel Compiler... the
./configure step runs smooth if using gcc and gfortran, but when using icc
and ifort it gives me the following warnings:

configure: WARNING: serial/parallel compiler mismatch detected
configure: WARNING: parallel compiler mpif90 uses gfortran, but serial
compiler is ifort

looking it up, I found a previous email in the mailing list (
http://www.democritos.it/pipermail/pw_forum/2009-June/013265.html) stating
that

you have a mismatch between parallel (mpif90) and
serial (gfortran) compiler. This is something
"configure" warns you about. Use
"./configure F90=gfortran", or, better, install
a mpif90 compiler that uses ifort

I tried to reinstall OpenMPI, using icc and ifort to compile its source, but
the conflict is still there... Is there anyway to make mpif90 use ifort ? or
is there any other parallel compiler using ifort?
