The error message was that it has a missing symbol, namely,

       blas_zhemv2_x_

I'm not real sure how to read this symbol  but try

      nm libblas.a | grep  _zhemv2

and see if the symbol is defined.

Note, I don't have this symbol in my libraries but I'm using different
versions of the libraries.

Please post your site.cfg file found in <OS
DIRECTORY>/python2.6/site-packages/numpy/distutils.

Is it possible you didn't add the BLAS libraries to the site.cfg file?
