This is the 3rd time I have reported this problem and a fix.

Build was successful after a change in distutils. 

Core 2 Duo, Debian Etch-32, Python 2.5, icc 10.1, ifort 10.1, & mkl
10.0. MKL & the compilers were installed to their default
locations: /opt/intel/mkl/, /opt/intel/cc/, /opt/intel/fc/
Installation will not interfere with earlier versions.


NumPy site.cfg for MKL 10.0
==========================================
[DEFAULT]
library_dirs=/opt/intel/mkl/10.0.011/lib/32
include_dirs=/opt/intel/mkl/10.0.011/include

[mkl]
libraries=mkl,guide

[lapack_info]
libraries=mkl_lapack,mkl,guide
==========================================


Changes in distutils:
=========================================================
In MKL 9.1 & 10.0, mkl_lapack32 & mkl_lapack64 no longer
exist. They were replaced by /32/mkl_lapack and
/64/mkl_lapack. As a result,
numpy-1.04/numpy/distutils/system_info.py 
needs to be changed:

    #lapack_libs = self.get_libs('lapack_libs',['mkl_lapack32','mkl_lapack64'])
    lapack_libs = self.get_libs('lapack_libs',['mkl_lapack'])

If the above change is not made numpy builds, but without using MKL.

In numpy-1.04/numpy/distutils/ccompiler.py change:
    #cc_exe = 'icc'                #works, but is suboptimal
    cc_exe = 'icc -msse3 -fast'    #adjust to suit your cpu
=========================================================

Running the command below (all one line) from the numpy-1.04 directory
python setup.py config --compiler=intel build_clib
  --compiler=intel build_ext --compiler=intel install
  > inst.log

Gave this inst.log:
