Fully working CPython of either version requires ports of lots of open 
source packages.  The 2.7 has a lot of them but the last time I looked, 
several were were way behind the Linux versions.

I have done some test builds of Python3, and got the GNV to run the 
python3 build procedure up to the point it starts running tests.  The 
first thing it needs for the tests is libffi, which I have not had time 
to try the code that Hartmut Becker worked out for it.

But much of the functionality needs stuff that also fails when I try to 
run gnulib tests.

https://sourceforge.net/p/gnv/wiki/Gnulib%20Assist/ documents the issues 
that I have found and my progress on it.
