Python 2.6 release schedule : http://www.python.org/dev/peps/pep-0361/

I was slightly out on the dates, but in 3 months Python 2.6 will do it's
last ever release, and there will be no security fixes going forward. "It's
dead Jim." Basically any upstream python modules that still support Python
2.6 are rare now and getting rapidly rarer. Python 2.6 + 3.x is
substantially harder than 2.7 + 3.x.

self contained build with the standard library on it, and then use that for
