pip has a --global-option flag

if you dont have root you can get a virtual enviroment no root is needed to get one and your path will be in home

curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.10.1.tar.gz
tar xvfz virtualenv-1.10.1.tar.gz
cd virtualenv-1.10.1.tar.gz
python virtualenv.py myVE

then your path is set in your home:

cd myVE/bin
./python

>>> import sys
>>> sys.path
['', '/home/foobar/temp/virtualenv-1.10.1/myVE/lib/python33.zip', '/home/foobar/temp/virtualenv-1.10.1/myVE/lib/python3.3', '/home/foobar/temp/virtualenv-1.10.1/myVE/lib/python3.3/plat-linux', '/home/foobar/temp/virtualenv-1.10.1/myVE/lib/python3.3/lib-dynload', '/usr/lib64/python3.3', '/usr/lib/python3.3', '/usr/lib/python3.3/plat-linux', '/home/foobar/temp/virtualenv-1.10.1/myVE/lib/python3.3/site-packages']

This was a helpful thread. Just to add on to this, you can also use pip without root if you pass the --user flag at the end:

For example, if you're using python-v2.7, the above command installs the python package to /home/username/.local/lib/python2.7/site-packages
