Virtualenv for updated python27

I installed virtualenv when Python was 2.6. Now I have updated python to 2.7.3. And in normal situations, python27 is working because I set the path properly.

But when it comes to virtualenv, it is not.

How can I use python27 for virtualenv by default?

Code:
% mkvirtualenv --no-site-packages --python=/usr/local/Cellar/python/2.7.3/bin/ py27 


gives an error

Code:
/usr/local/bin/virtualenv:5: UserWarning: Module pkg_resources was already imported from /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.pyc, but /Library/Python/2.6/site-packages is being added to sys.path
  from pkg_resources import load_entry_point

  from pkg_resources import load_entry_point

How about running as root? put sudo in front of that command.
% sudo mkvirtualenv ...
