use "pkg info | grep py" and verify that the packages did install
correctly, from one of my systems running Python with py-sqlite3, it
works fine. I am running WeeWX on this system which even though I am
using mySQL for most of the data, it still has some dependency on
sqlite3, so not only does it import, but I have applications using
py-sqlite3.

make sure that the py27_sqlite3 or py34-sqlite3 depending on which you
are trying to use is installed. I have Python 2.7 set as system default
do to some requirements on the software. But also have Python 3.4
installed for some custom system maintenance scripts I have written,
those fortunately don't require any other python dependencies so it
seems to work OK having both installed.
