If you've installed python somewhere other than /usr/local, then you
should be able to follow the install directions exactly with just a

python setup.py install

as long as the 'python' above is the one in your dir directory. It
should install the libraries inside this python installation.

You can also specify any random alternate location for installation
with:

python setup.py install --prefix=wherever/you/want/it

Hope this helps!
