This igraph(0.1.11) is the one you installed, while this igraph(0.7.1) is the one you need (and the well-known iGraph).

Using pip (once you've installed it), Just do:

sudo pip uninstall igraph

Then install the python-igraph-0.7.1 package, using either pip or apt-get as mentionned in comments below:

sudo pip install python-igraph
