# Install virtualenv and virtualenvwrapper
# Once you make your first virtualenv, you'll have 'pip' in there.
# I got bitten by trying to install a system-wide (i.e. Python 2.6) version of pip;
# it was clobbering my access to pip from within virtualenvs, and it was frustrating.
# So these commands will install virtualenv/virtualenvwrapper the old school way,
# just so you can make yourself a virtualenv, with pip, and then do everything Python-related
# that you need to do, from in there.

When run as sudo, this happens.

./python: line 48: easy_install-3.5: command not found
./python: line 49: easy_install-3.5: command not found

If you run those lines when the script finishes, you got successful results.
