This will get you python3.5 which I infinitely prefer over 3.4. 
But you said you wanted to use 3.4 ...

What I found out.
https://bugs.python.org/issue25151
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732703

pyenv is going away.  use python -m venv instead, if you want a 
venv.  You will never (unless somebody does a backport, which seems
very unlikley) be able to get a venv with 2.7.

I've long ago aliased virtualenv to v, so things aren't as clunky
for me.
