Script for compiling Python 2.7.9 on Ubuntu 14.04 LTS

python-2.7.9_install.sh

#!/bin/sh
# Script for compiling Python 2.7.9 on Ubuntu 14.04 LTS and installing it to /usr/local
# * Source files are downloaded and left at /usr/local/src
# * Uses checkinstall to generate a deb package, so it will take a while.
# * Can be uninstalled using 'dpkg -r private-compiled-python2.7'
# * Uncomment line 57 if you *don't* want to install virtualenv and supervisor
# * Gists will be downloaded if supervisor's conf or init script doesn't exist.
# * You'll need to add /usr/local/bin to your PATH if it's not already
