When i do the command python i get the folowing.

Python 2.6.8 (unknown, Apr  9 2013, 19:12:12) 

[GCC 4.7.2] on linux3

Type "help", "copyright", "credits" or "license" for more information.

I want to have python2.7 back to that command. so i have this:

Python 2.7.3 (default, Sep 26 2012, 21:51:14) 

[GCC 4.7.2] on linux2

Type "help", "copyright", "credits" or "license" for more information.

I have already tried to change the symlink in /usr/bin/python but don't work :(. I am also afraid that some programs will break.
