Actually the stable upstream release for dev-python/httplib2-0.7.1 has some major issue. Please add at least the patches used in the ubuntu oneric package http://archive.ubuntu.com/ubuntu/pool/main/p/python-httplib2/python-httplib2_0.7.1-1ubuntu1.debian.tar.gz Upstream ref bug: http://code.google.com/p/httplib2/issues/detail?id=154 https://bugs.launchpad.net/ubuntu/+source/python-httplib2/+bug/839826
A new upstream version containing the patches has been released, I opened a new bug #391371 for it
Closing this one.
