Getting graphviz working...?

[Eric Gorr]

I was hoping someone could help me get things configured properly for  
dot on my Mac running 10.4.8.
I am using dot 2.8

My simple graph file is:



digraph test123 {
        a -> b -> c;
}


when I run dot from the terminal, I get the following output:



The plugin configuration file:
         /opt/local/lib/graphviz/config
                 was successfully loaded.

dot: allocating a 20K PaletteColor GD image
Error: fontconfig: Didn't find expected font family. Perhaps URW Type

I am not certain how to work around this font problem, when  
installing from MacPorts.

Any suggestions?
