Please set that up, and ship us a doc patch for INSTALL explaining
how this needs to be done for the Mac.  I do intend to move us to 3.x,
but there is enough Python code that this can't be done quickly.

The intention is to require 2.6 for runtime.  That is pretty safe at this point;
even LTS Centos has it, I believe.
