How to install a python package for one particular webapp in WebFaction

Both of the following examples are based on a Django 1.7 / Python 3.4 app.

Example 1: ReportLab

$ pip3.4 install --user -U setuptools
$ cd ~/webapps/APP
$ PYTHONPATH=$PWD/lib/python3.4 pip3.4 install \
  --install-option="--install-scripts=$PWD/bin" \
  --install-option="--install-lib=$PWD/lib/python3.4" \
  reportlab==3.1.8

$ python3.4 manage.py shell
>>> import reportlab
>>> reportlab.__file__ # to verify

Example 2: django-taggit

$ pip3.4 install --user -U setuptools
$ cd ~/webapps/APP
$ PYTHONPATH=$PWD/lib/python3.4 pip3.4 install -t $PWD/lib/python3.4 \
  django-taggit

$ python3.4 manage.py shell
>>> import taggit
>>> taggit.__file__ # to verify

The exact method to use depends on how the package is built.
