-- ellson -- Are you by any chance compiling graphviz locally on a RedHat system?

There is a "feature" in /bin/sort of recent redhat releases that the default sort order has changed and no longer matches the C sort order impied by strcmp().

The work around is to "export LC_COLLATE=C" into your environment before building graphviz. (The bug affects the compile-time sorting of color names used for name->rgb translation.)

If you're seeing this problem with our binary releases then we have this problem somewhere in our build process.
