Answer 2

From the information provided and order presented, it looks like you installed python 3.4 from source BEFORE making installing the sqlite-dev package available. If you watch the python 3.4 install closely you would have noticed any number of modules it did not build out (one of which would be _sqlite3).

Solution: Reinstall 3.4 now that sqlite3 dev is available.
