      I'm not totally sure I understand what you are asking but here's a
      <br>
      guess.  Today, probably the most widely-used solution to provide
      <br>
      packages with pre-built C extension modules is to use setuptools
      or its
      <br>
      Distribute fork and build a bdist egg which can then be downloaded
      and
      <br>
      installed with the easy_install command.
      <br>
      <br>
      Note the whole area of binary distributions for Python is one that
      is
      <br>
      now under intense active development.  The standard library
      replacement
      <br>
      for binary eggs will be wheels;  various tools to support building
      and
      <br>
      installing them are being designed and implemented and are
      expected to
      <br>
      be part of Python 3.4 with downloadable support for selected
      earlier
      <br>
      releases.  It's all happening on the distutils-sig and in various
      PEPs.
      <br>
      Nick Coughlan, the core developer leading the design effort, gives
      an
      <br>
      overview of the current plans here:

    <big><big>I understand that easy_install does not make provision<br>
        for BLAS and similar linear algebra optimizations.<br>
        <br>
        A few weeks back, I reported that a test ran more slowly<br>
        on 3.2 than on 2.7.  This was attributed, by one respondent,<br>
        to the absence of these optimizations when using easy_install.<br>
        <br>
        easy_install was used for both of my installations.<br>
        <br>
        I have not yet sorted out how to use the setup.py so<br>
        that the optimizations are included.<br>
