Here it is
In [2]: scipy.show_config()
amd_info:
    libraries = ['amd']
    library_dirs = ['/sw64/lib']

umfpack_info:
    libraries = ['umfpack', 'amd']
    library_dirs = ['/sw64/lib']

lapack_opt_info:
    extra_link_args = ['-Wl,-framework', '-Wl,Accelerate']
    extra_compile_args = ['-msse3']
    define_macros = [('NO_ATLAS_INFO', 3)]

blas_opt_info:
    extra_link_args = ['-Wl,-framework', '-Wl,Accelerate']
    extra_compile_args = ['-msse3',
'-I/System/Library/Frameworks/vecLib.framework/Headers']
    define_macros = [('NO_ATLAS_INFO', 3)]

As far, as I understand, numpy and scipy are build against Mac OS X Accelerated
framework, which includes lapack and blas libs, but as I've wrote recently, when
I'm building case a crash
