(graphite) $ pip install --upgrade pip wheel setuptools gunicorn whisper
(graphite) $ pip install carbon --install-option="--prefix=/opt/graphite" --install-option="--install-lib=/opt/graphite/lib"
(graphite) $ pip install graphite-web --install-option="--prefix=/opt/graphite" --install-option="--install-lib=/opt/graphite/webapp"
