title: Build Boost with multiple Python versions
body: <p>I use several versions of Python on my computer : <code>2.6.6</code>, <code>2.7.6</code> and <code>2.7.9</code>. When I compile Boost with boost-python, I have to give the Python to use in argument. If I want compatibility, <strong>have I to compile Boost for each Python version ?</strong> (it's quite huge !) Or is there a way to use only one build of Boost with several python versions ?</p>
