Can I use another python implementation via virtualenv / virtualenvwrapper?

Question

After some time of searching (maybe this is not enough, but I don’t think I am doing this), I could not find compatibility information for other Python implementations in virtualenv / virtualenvwrapper. By "different implementation" I mean things like PyPy, IronPython, Cython, Jython ...

for example, I can create virtualenv for another version of python using the following code.

mkvirtualenv -p /usr/bin/python2.6 new_venv

but when I tried to create virtualenv for PyPy, follow these steps:

mkvirtualenv -p /usr/bin/pypy new_venv

System

causes some error.

EDIT: I am using virtualenvwrapper-win. he throws

Running virtualenv with interpreter C:\pypy2-v5.8.0-win32\pypy.exe
New pypy executable in C:\Users\fangming.zfm\Envs\test-123\bin\pypy.exe
Installing setuptools, pip, wheel...done.
system cannot find the path specified.

why can't we do this? is it due to lack of interest or technically unfeasible?
