i am sorry, i am not sure if i have come to the correct place or this is a bug. i am now trying to download the graphviz for solaris. but the download link http://www.graphviz.org/Download_solaris.php does not present any package to install.
[north] did we ever have regular builds of Solaris working in the first place? does Solaris have a packaging tool?
maybe we should drop this.
