distinguish between PyPI and Debian python packages

[Szépe Viktor <viktor@szepe.net>]

Good morning!

Could you help me to get `pip freeze` and `pip list` to display only  
packages installed by pip and to exclude packages coming from a Debian  
package?

The only way I've found is

import pip
for dist in pip.get_installed_distributions():
    if dist.location.startswith('/usr/local/lib/python'):
        print dist.project_name

Could you patch upstream with this option?

Thank you!
