Additional info
This was reported by a MacPorts user at https://trac.macports.org/ticket/67760 and I can confirm the issue on my system. /opt/local/lib/graphviz/libgvplugin_vt100.6.dylib did get built and installed apparently normally, however /opt/local/lib/graphviz/config6 doesn't contain any mention of vt100. I reran sudo dot -c
which generated an unchanged config6 file and no error messages.
