In the current numpy svn there are at least two distutil problems:
In  system_info.py, the line:

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

will not work with MKL 9.1 because the '32' and '64' have been
removed. The line below works for me (but of course it won't work for
the old MKL 8.1, so there probably should be a version check).

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

In fcompiler/intel.py, the line(s) 

'version_cmd'  : ['<F77>', None],

causes the scipy build to fail when ifort 10.0 (and, ifort 9.1, I think)
is used. Following George Nurser's lead, I changed all instances to:

'version_cmd'  : ['<F77>', '-V'],

and now scipy svn builds. ('-V' may not be correct for the visual

The problem of scipy ignoring 

cc_exe = 'icc ...

in intelccompiler.py and using gcc remains.
