I give you, one access to our computer. I am not in my office these two 
following days but you can contact me since monday. If you have a system 
problem, you can send a mail to Bruno.Bzeznik@imag.fr

1. We have two versions of python installed to test scipy installation:
* *one compiled with gcc* (usr/local/stow/Python2.4.4)

* t*he other with the intel compiler* "icc" 

You have acces on these two directories.

2. I put in your *.bashrc the environment to use the Intel compilers *

3. The *scsl library *(scientific library optimized on our cluster with intel compilers) is in */usr/lib (compiled with Intel Fortran compiler)
*(On Itanium, the install procedure of ATLAS want to use Intel compilers, we can forced it to use Gnu compilers but we obtain bad optimizations)*
4. I attached on my mail the file *'site.cfg*' used to install scipy and numpy

4. I attached on my mail a file named *"whatWeHaveDone.txt" *in which I give you again what we have done to install numpy and scipy.

remarks: It seem that it's a bug in the part of program which extract 
the intel version compiler. *An additional test is made in 
numpy/distutils/command/build_ext.py to test this version *(ifort -V), 
there is no version test in numpy/distutils/command/build_clib.py.

I tried to change this test in 
it doesn't run.

thanks for your help
