# First get the setup script for Setuptools:
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py

# Then install it for Python 2.7 :
python2.7 ez_setup.py

# Now install pip using the newly installed setuptools:
easy_install-2.7 pip

# With pip installed you can now do things like this:
pip2.7 install [packagename]
pip2.7 install --upgrade [packagename]
pip2.7 uninstall [packagename]

# Install virtualenv for Python 2.7 and create a sandbox called my27project:
pip2.7 install virtualenv
virtualenv-2.7 my27project

# Check the system Python interpreter version:
python --version
# This will show Python 2.6.6

# Activate the my27project sandbox and check the version of the default Python interpreter in it:
source my27project/bin/activate
python --version
# This will show Python 2.7.X
deactivate
