Import error on Ubuntu 15.04

I've installed pygraphviz 1.3.1 with pip on Ubuntu 15.04, and when I try to import I get the following error:

---------------------------------------------------------------------------

ImportError: /home/greff/venv/py2/local/lib/python2.7/site-packages/pygraphviz/_graphviz.so: undefined symbol: Agundirected

Any ideas?

It looks like same as #71. Try installing with direct path to graphviz

pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"

That did the trick. Thank you!
