Hi Tiziano,

See

http://projects.scipy.org/scipy/scipy/ticket/795
  
I use openSUSE 10.2 (X86-64)

>>> show_config()
atlas_threads_info:
   NOT AVAILABLE

blas_opt_info:
     libraries = ['f77blas', 'cblas', 'atlas']
     library_dirs = ['/usr/local/lib/atlas']
     define_macros = [('ATLAS_INFO', '"\\"3.7.11\\""')]
     language = c

atlas_blas_threads_info:
   NOT AVAILABLE

lapack_opt_info:
     libraries = ['lapack', 'f77blas', 'cblas', 'atlas']
     library_dirs = ['/usr/local/lib/atlas']
     define_macros = [('ATLAS_INFO', '"\\"3.7.11\\""')]
     language = f77

atlas_info:
     libraries = ['lapack', 'f77blas', 'cblas', 'atlas']
     library_dirs = ['/usr/local/lib/atlas']
     language = f77

lapack_mkl_info:
   NOT AVAILABLE

blas_mkl_info:
   NOT AVAILABLE

atlas_blas_info:
     libraries = ['f77blas', 'cblas', 'atlas']
     library_dirs = ['/usr/local/lib/atlas']
