After my build and install of graphviz, running dot -c fails (it evidently failed as well during the build/install). I get no error messages regardless of whether I run under sudo, and no config6 file is created. All the libgvplugin… libraries are present in lib/graphviz.

Any suggestions on how I could track down the cause? Some missing/corrupt input, some environment setting I need to establish?
