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. render : canon cmap cmapx dia dot fig gd gd2 gif hpgl imap ismap jpeg jpg mif mp pcl pic plain plain-ext png ps ps2 svg svgz vrml vtx wbmp xdot layout : circo dot fdp neato nop nop1 nop2 twopi textlayout : device : usershape : png-gd dot: fontname=Times-Roman fontpath=[internal times] network simplex: 3 nodes 2 edges 0 iter 0.00 sec mincross: pass 0 iter 0 trying 0 cur_cross 0 best_cross 0 mincross test123: 0 crossings, 0.00 secs. network simplex: 5 nodes 4 edges 0 iter 0.00 sec routesplines: 2 edges, 6 boxes 0.00 sec dot: allocating a 20K PaletteColor GD image Error: fontconfig: Didn't find expected font family.
