title: Virtualenv issue with flask-werkzeug
body: <p>I have installed virtualenv along with flask, werkzeug, jinja2 and SQLAlchemy. I was following the tutorial mentioned on the flask website and i came across the below error when executing flask code</p>
  
  <pre><code> Traceback (most recent call last):
    File "hello.py", line 1, in ?
      from flask import Flask
    File "/root/myproject/env/lib/python2.4/site-packages/Flask-0.7dev_20110211-py2.4.egg/flask/__init__.py", line 18
      from .app import Flask, Request, Response
           ^
  </code></pre>
  
  <p>What i feel is that virtualenv contains python 2.4 and in the documentation of flask it is mentioned that flask supports python 2.5. So maybe that might be the problem or it might be someother issue. Please help me out on this.</p>
  
  <p>Secondly i would like to know the process of getting the latest virtualenv which has Python 2.7 or any tips on how to install it on virtualenv.</p>
  
  <p>I am using CentOS</p>
  
  <p>Thank You in Advance</p>
