Edit:

Sorry I posted that without trying it out just by looking at the manual, but I managed to solve the problem. Here are the steps I did to make it run.

1)

install optional package dot2tex

2)

install optional package graphviz from the same page (http://www.sagemath.org/packages/optional/)

3)

At the terminal type $sage -sh $easy_install pygraphviz

That way I was able to run a simple pygraphviz example.
