title: example of python distutils package code that depends on other modules?
body: <p>can someone point out a simple example of making a Python package using distutils that depends on <em>other</em> python modules being installed, e.g. numpy (a particular version) and scipy?  I found very simple examples online but could not find an example that depends on a known package. I want to find the easiest system where such dependencies are installed for the user when the user installs the package I am defining using setup.py install.  thanks.</p>
