How do you solve this VirtualEnv Running on Jython Error?

I am able to successfully run virtualenv on python, not but on jython (version 2.5.2). What could be the problem and how do I fix this?

Below is the error: 

Susans-MacBook-Pro:Intro_Jython susantan$ virtualenv -p jython susan_env_jy
Running virtualenv with interpreter /Users/susantan/jython2.5.2/bin/jython
ERROR: None
ERROR: this script requires Python 2.6 or greater.
Susans-MacBook-Pro:Intro_Jython susantan$ virtualenv -p python susan_env_jy
Running virtualenv with interpreter /usr/bin/python
New python executable in susan_env_jy/bin/python
Installing setuptools, pip...done.

From the Jython website:

The most current stable release of Jython is 2.5.3. For production purposes, please use this version.

From your error message:

ERROR: this script requires Python 2.6 or greater.

This is probably the cause of the problem. Jython has a 2.7beta1 which you could try.

Edit: from the virtualenv website, it looks like they dropped support for Python 2.5 in v1.10:

1.10 (2013-07-23) ~~~~~~~~~~~~~~~~~

  • BACKWARDS INCOMPATIBLE Dropped support for Python 2.5. The minimum

You will have to install an earlier version of virtualenv to support Jython 2.5.x

Here is a link to the previous version (1.9.1) https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.9.1.tar.gz - You should be able to install this by extracting the package and running jython setup.py install from within the folder.
