At little late to the party, but, one thing that worked for me was to install pkg-config . Looks like easy_install / pygraphviz really prefers that on Ubuntu.
Unable to install pygraphviz from pip? Can't find graphviz.

Your graphviz installation could not be found.
Either the graphviz package is missing on incomplete
(binary packages graphviz-dev or graphviz-devel missing?).
If you think your installation is correct you will need to manually
change the include_path and library_path variables in setup.py to
point to the correct locations of your graphviz installation.
The current setting of library_path and include_path is:
library_path=None
include_path=None
