Probably not: The graphviz libraries aren't supposed to be used by other
applications anyway, that's why they're not in the standard library path.
The graphviz licence is incompatible with the GPL as well, prohibiting GPL'd
applications from linking to the libraries (Fun fact: There is a GPL'd
pygraphviz binding around (https://networkx.lanl.gov/pygraphviz/), which is
'based' on the (non-GPL'd) code that his port uses to boot. Don't even think
of porting that. =) )
