Comment(by rgommers):

 That doesn't quite work:
 {{{
   File
 "/Users/rgommers/Code/scipy/scipy/sparse/linalg/eigen/arpack/arpack.py",
 line 43, in <module>
     import _arpack
 ImportError:
 dlopen(/Users/rgommers/Code/scipy/scipy/sparse/linalg/eigen/arpack/_arpack.so,
 2): Symbol not found: _cblas_sdot_sub
   Referenced from:
 /Users/rgommers/Code/scipy/scipy/sparse/linalg/eigen/arpack/_arpack.so
   Expected in: dynamic lookup
 }}}
 It not immediately obvious to me why. Perhaps {{{cblas_sdot}}} needs a
 letter appended, just like {{{cblas_zdotu}}} / {{{cblas_zdotc}}}?
