Adding matplotlib to locally installed blender

Update: Unless you hate virtual environments, I found a better way:

I had some trouble getting a local blender 2.75 in my home directory to use matplotlib - using the system wide python3.4 for some reason failed, so in the end I just copied over files to the local version until blender stopped complaining.
Required packages for Ubuntu 14.04: python3-pyparsing, python3-dateutil¸ python3-matplotlib, python3-cycler, python3-six. Using the following destination root directory ~/bin/blender/2.75/python/lib, I copied these files and folders:

source	destination
/usr/lib/python3/dist-packages/pyparsing.py	python3.4/site-packages/
/usr/lib/python3/dist-packages/dateutil	python3.4/site-packages/
/usr/lib/python3/dist-packages/matplotlib	python3.4/site-packages/
/usr/lib/python3/dist-packages/mpl_toolkits	python3.4/site-packages/
/usr/lib/python3/dist-packages/pylab.py	python3.4/site-packages/
/usr/lib/python3/dist-packages/cycler.py	python3.4/site-packages/
/usr/lib/python3/dist-packages/six.py	python3.4/site-packages/
/usr/lib/python3.4/distutils	python3.4/

A bit ridiculous for just wanting to use their colour maps, but there you go… Note: Still works for blender 2.77/Python 3.5/Kubuntu 16.04. Replace Python3.4 with Python3.5.
