[Tutor] trouble installing library

[Danny Yoo]

According to the documentation in:

    http://www.virtualenv.org/en/latest/

and:

    https://pypi.python.org/pypi/virtualenv

the "Installation" section in the documentation walks through what you
need to do to install the software.


Can you use Python's package managment system "pip" to handle the work
of installing the 'virtualenv' package?
