Thanks Dave! With those direction I also found a good example here:

	http://brockwoolf.com/how-to-use-dynamic-libraries-in-xcode-31-using-fmod

It turns out that two of the Graphviz dynamic libraries also depended on other dynamic libraries, so I needed repeat the install_name_tool command on the libraries themselves. In case someone runs into this problem and finds this thread, below is my "Run Script" that gets called at the end of the build.
