Pip has an option to upgrade a package (_pip install -U_), however it always downloads sources even if there is already a newest version installed. If you want to check updates for all installed packages then some scripting is required.

This script checks if there is a newer version on PyPI for every installed package. It only prints information about available version and doesn't do any updates. Example output:

distribute 0.6.15                        0.6.16 available
Baker 1.1                                up to date
Django 1.3                               up to date
ipython 0.10.2                           up to date
gunicorn 0.12.1                          0.12.2 available
pyprof2calltree 1.1.0                    up to date
profilestats 1.0.2                       up to date
