Description true 2012-10-01 06:26:24 UTC 
like writen here -> https://github.com/scikit-learn/scikit-learn/pull/766

'ATLAS' detection in numpy is not necessarily reliable and does not always work (e.g. see Gentoo's patches [1,2]).

Removing the ('NO_ATLAS_INFO', 1) in blas_info.get('define_macros', [])) part enables sklearn to be properly compiled with ATLAS support on Gentoo & Gentoo Prefix (i.e. Gentoo in non-root user space).'

but:
ImportError: /usr/lib64/python2.7/site-packages/sklearn/cluster/_k_means.so: undefined symbol: cblas_ddot

$ eselect cblas list
Installed CBLAS for library directory lib64
  [1]   atlas
  [2]   atlas-threads *
  [3]   gsl
  [4]   reference

under root everything is ok.
