easy_install pip == [Errno 8] nodename nor servname provided, or not known

Question

I have troubles installing pip for python 2.7.3 installed via pythonbrew:

pythonbrew update --master
pythonbrew install 2.7.3 --force

This fails on the final stage hanging when trying to fetch pip from pip.openplans.org:

Installed /Users/andrei/.pythonbrew/pythons/Python-2.7.3/lib/python2.7/site-packages/distribute-0.6.28-py2.7.egg

Running easy_install pip also results in the same error. Of course, I can still clone pip repo and install it manually, but would be nice to know why it fails via easy_install. Any idea?

I had a similar problem; the command was failing in iTerm2, but not in the default OS X Terminal. Restarting iTerm2 fixed the issue.
