Agreed. I tend to keep my own Python installation in ~/opt, and then
use the usual `python setup.py install` to install modules. You just
need to make sure you have $HOME/opt/py/bin in your $PATH before the
system python (or else explicitly specify `~/opt/py/bin/python
setup.py install` when you install modules).

If your *system* Python needs modules, you install those with your OS
package management utility.
