Well, I proceeded as suggested, and things are no longer broken:
user at host$ pip --version
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
user at host$

(The same output before and after doing the "source .bashrc")

I guess that I'll just ignore the messages that tell me to upgrade
my pip.

Thanks to all!
