How to install Contour plugin?

How to install Contour plugin?

For the time being, my interest  was installing Lionel Roubeyrie's Contour plugin in Ubuntu mode but I was first greeted by a prerequisite because matplotlib module was missing. A search on the Internet let me to try out purely the matplotlib module installation script which solved that but was greeted by another missing module... shapely.geometry. I hate that and who knows what other modules will be missing. Some search later, I eventually ended with the following scripts which installed the Contour plugin and after activated under Fetch Plugin, it appeared in the menu bar:

wget http://python-distribute.org/distribute_setup.py

sudo python distribute_setup.py

wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py

sudo python get-pip.py

# to install from git source

sudo apt-get update

sudo apt-get install git

sudo apt-get install python-dev

sudo pip install numpy

sudo pip install cython

sudo apt-get install libproj-dev

# install geos 

sudo apt-add-repository ppa:sharpie/for-science

sudo apt-get update

sudo apt-get install libgeos-dev

sudo pip install shapely

sudo apt-get install python-scipy

sudo pip install pyshp

sudo apt-get install python-imaging

sudo apt-get build-dep matplotlib

wget https://github.com/downloads/matplotlib/matplotlib/matplotlib-1.2.0rc2.tar.gz

tar xzf matplotlib-1.2.0rc2.tar.gz

cd matplotlib-1.2.0rc2

sudo python setup.py install

At least, I got the Contour plugin in the menu bar, I have yet to try it out because I have to go out. (Family quality time is also important as QGIS)

Update:

Contour Plugin under Windows mode installed without any hiccup so I decided to give it a try. I got some unexpected results
