title: Mac Python pointing to different site-packages after python upgrade - How do i point all site-packages to correct python version?
body: <p>I am trying to upgrade my Mac from 2.6 to 2.7 and everything went fine except for some libraries are being used from 2.6 now instead of 2.7, any idea how I can point all the new libraries to 2.7?  Basically I am trying to install yolk for 2.7 but it says that its already installed (under 2.6).</p>
