The latest version is 1.6.1
use sudo pip install virtualenv, it will update the version if you use the version 1.4.x.
He recommended using pipover easy_install here to find out the reasons.

no no. The newer installed automation version of virtualenv overrides the obsolete version.

if I remember at the moment, use this to install:

sudo easy_install virtualenv==1.6.1
