title: uninstall ipython mac os x
body: <p>I've just installed a new ipython 0.11 on Mac OS X from sources. Unfortunately it turned out that it lacks back-compatibility with its previous versions, so all the scripts I need do not work. 
  After that i installed a 0.10 version of ipython from macports, hoping it would replace the current one (yep, maybe it wasn't a good idea - things gone even more complicated). But it didn't, and my scripts are still using the 0.11 version of ipython</p>
  
  <p>The only thing I need is to make my scripts working. So I need somehow uninstall iPython v.0.11, or make version 0.10 a preferred to use</p>
  
  <p>Thanks for any help! </p>
