body: <p>I have installed python 2.7.3 on CentOS 6 with thse instructions </p>

  <p>I have added aliases to bash_profile of both root and myuser for new python.
  Now when I write python to shell, it runs python2.7.3 correctly from both users.</p>
  
  <p>However, if I write sudo python it stills runs old version python2.6.6</p>
  
  <p>What could be the problem?</p>
