title: Can EPD Python and MacPorts Python coexist on OS X (matplotlib)?
body: <p>I've been using MacPorts Python 2.6 on OS X 10.6. 
  I am considering also installing the Enthought Python Distribution (EPD) on the same machine because it comes preconfigured with matplotlib and other nice data analysis and visualization packages.</p>
  
  <p>Can the two Python distributions co-exist peacefully on the same machine? 
  What potential problems will I have to look out for (e.g., environment variables)?</p>
  
  <p>I know that building matplotlib through MacPorts is an option, but the process is lengthy (on the order of a full day) and there are open questions about compiling some dependencies on  64bit Intel.</p>
  
  <p>I would like to know about the tradeoffs before committing to one of the two approaches.</p>
