How to install virtual environment with python 3 without upgrading existing version of python on my OSX which is 2.7

Question

Is it possible to have a virtual environment setup with python 3 if my OS has python 2.7 installed, I am using "$ virtualenv python3env -p python3" but its trying to look for a PATH for python3 on my system. Is there a work around for this problem?
