On Ubuntu 14.04, there is a problem in auto detecting graphviz library and include files. If you follow the steps below probably you'll be safe.

1) sudo apt-get install graphviz libgraphviz-dev pkg-config python-pip
2) pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"
