Sure, that's a good call to know about. It looks like it's not using the same setting for library_dirs as what's in my LD_LIBRARY_PATH.

>>> numpy.show_config()
blas_info:
    libraries = ['blas']
    library_dirs = ['/usr/lib']
    language = f77

lapack_info:
    libraries = ['lapack']
    library_dirs = ['/usr/lib']
    language = f77

atlas_threads_info:
  NOT AVAILABLE

blas_opt_info:
    libraries = ['blas']
    library_dirs = ['/usr/lib']
    language = f77
    define_macros = [('NO_ATLAS_INFO', 1)]

atlas_blas_threads_info:
  NOT AVAILABLE

lapack_opt_info:
    libraries = ['lapack', 'blas']
    library_dirs = ['/usr/lib']
    language = f77
    define_macros = [('NO_ATLAS_INFO', 1)]

atlas_info:
  NOT AVAILABLE

lapack_mkl_info:
  NOT AVAILABLE

blas_mkl_info:
  NOT AVAILABLE

atlas_blas_info:
  NOT AVAILABLE

mkl_info:
  NOT AVAILABLE

>>> 
ia3n@gaussian:~/theano/2_atlas% echo $LD_LIBRARY_PATH
/usr/lib/atlas/sse2

Can you give us the output of numpy.show_config()?
