Are you on the unreleased Jessie? And why do you even > need 2.6 as opposed to 2.7? I am on Debian 7.6, Wheezy (Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux). Wow, so it is really this simple? This was actually the first option I considered, but I was sooooo paranoid to ruin my default Python version. Reason why I need Python 2.6? The script needs to run on a server that turned out to have Python 2.6. It is beyond my power to upgrade the Python version. Thanks all! -- https://mail.python.org/mailman/listinfo/python-list
