!MULTIPLE PYTHON VERSIONS IN FREEBSD / izabeera and dryobates

""It’s easy to install multiple versions of Python with FreeBSD ports.

""I had a problem with sqlite3:
 ImportError: No module named _sqlite3

""With default Python version I can install it from "databases/py-sqlite3" doing "make install" like above. How to install it for Python3.x? There's no py34-sqlite3 port.

""The key is to set PYTHON_VERSION environment variable:

 $ cd /usr/ports/databases/py-sqlite3
 $ make PYTHON_VERSION=3.2 install clean
 $ make PYTHON_VERSION=3.3 install clean
 $ make PYTHON_VERSION=3.4 install clean

*上記は 2014年の記事
