I reported this against graphviz, but no feedback has happened.  As for
git-core, was posted 5 months ago, and
nobody seems to know what the problem is.

This mac is all of two weeks old, so I'm loath to reinstall the operating
system.  I completely uninstalled and reinstalled MacPorts, and am getting
these exact same errors.

Any help or advice?
