You should apply the version actually committed (or something based on 
it).  https://hg.python.org/cpython/rev/7f99ac53014a/
This may be the same as the -3 patch but might have been tweaked.

You should remove the diff for Misc/NEWS, as it is not in your 
installation.  You can also do without the addition to 
Lib/test/test_ssl.py, or add it by hand.  If you can bet a generic patch 
program to just patch Lib/ssl.py, great.  But you could do this by hand.

However, I second the suggestion to install 2.7, especially if you can 
2.7.9, which has this patch, even if you have to download the source and 
compile.  2.7 is more compatible with 3.x than 2.6, and 2.7.9 has 100s 
of little bug fixes compared to 2.6.6.
