The python.org 3.4.x series of installers will likely never change from 
linking with Tk 8.5 by default.  That would break a number of important 
third-party Python packages that supply binary distributions built for 
the python.org OS X pythons, like matplotlib.  For Python 3.5, we will 
have the opportunity to change that.

File an update request for the tcl and tk ports on the MacPorts tracker.  
The project is usually very responsive to such requests.

https://trac.macports.org

Note that ActiveState hasn't yet released their versions of 8.6.2.

As Kevin Walzer points out, you *can* also build your own.  I still 
intend to provide a downloadable solution for 3.4.x and 2.7.x; I hope to 
get back to it shortly.  Sorry for the delay!
