Fantastic! *** Many thanks ***

Is there a way to convince him to look for the 64 Bit variant
under /opt/intel/mkl72/64 ??

Presently  the result is

#------------------
python scipy/distutils/system_info.py lapack_opt
lapack_opt_info:
lapack_mkl_info:
mkl_info:
  FOUND:
    libraries = ['mkl_ia32', 'mkl', 'vml', 'guide', 'pthread']
    library_dirs = ['/opt/intel/mkl72/lib/32']
    include_dirs = ['/opt/intel/mkl72/include']

  FOUND:
    libraries = ['mkl_lapack', 'mkl_ia32', 'mkl', 'vml', 'guide',
'pthread']
    library_dirs = ['/opt/intel/mkl72/lib/32']
    include_dirs = ['/opt/intel/mkl72/include']

( library_dirs = /home/baecker/python2/lib:/usr/local/lib:/usr/lib )
  FOUND:
    libraries = ['mkl_lapack', 'mkl_ia32', 'mkl', 'vml', 'guide',
'pthread']
    library_dirs = ['/opt/intel/mkl72/lib/32']
    include_dirs = ['/opt/intel/mkl72/include']
#----------------


I tried

[mkl_libs]    or [mkl_lapack]  or [mkl]
library_dirs = /opt/intel/mkl72/lib/64
include_dirs = /opt/intel/mkl72/include/

but non worked?

For the full scipy I suspect that we will run into
the single/double precision lapack routines problem
(libmkl_lapack32.so provides all the s* and c*
while libmkl_lapack64.so provides the d* and z* routines),
but one thing after another ... ;-)

Many thanks, Arnd
