It is a bit complicated because you need to build your own python
interpreter (the python.org one does not handle 64 bits AFAIK). You
could just install your python somewhere in your $HOME for example, and
whenever you use this python interpreter to build a package, it will
install it inside the site-packages of this python - so no clash with
existing python interpreters. There are also things like virtualenv and
co which can be considered if you need more than a couple of packages,
