First, mkl is NOT atlas.

mkl: http://www.intel.com/cd/software/products/asmo-na/eng/perflib/mkl/index.htm
atlas: http://math-atlas.sourceforge.net/

system_info assumes that atlas libraries are used
according to official instructions given in 

mkl and atlas are different libraries of optimized blas/lapack/.. 
libraries. So the problem boils down to adding mkl support to system_info.
Btw, then also fftpack, ufunc's, random could take advantage of mkl some 

Adding mkl support means implementing

class intelmkl_info(system_info):
     section = 'intelmkl'
     dir_env_var = 'INTELMKL'
     _lib_names = ['mkl']

class in system_info.py and adding required hooks to lapack_opt, blas_opt

The link
seems to be broken but to implement intelmkl support, one needs to know
how/where mkl libraries are installed and how to use them (the order of 
libraries, etc), this information should come with mkl, I couldn't find 
this information from internet.
