Target for graphviz-devel no longer exists

The target for graphviz-devel had been deleted on the target server:

[adam@tester]$ sudo /opt/local/bin/port install graphviz-devel
--->  Fetching graphviz-devel

The latest stable copy should be fetched - graphviz-working.tar.gz

You are way out of date. Run the following:

sudo port selfupdate
sudo port upgrade outdated
sudo port install graphviz-devel

Replying to adam@…:

The latest stable copy should be fetched - graphviz-working.tar.gz

Actually ports should not use a "latest" tarball, and should instead always use a versioned or dated tarball, as graphviz-devel does. Otherwise there would be no certainty that the tarball you got when you installed the port was the same one I got when I made the portfile. And we want that certainty, so much so that each portfile has checksums of the distfile so that if you get a different file, you get a checksum mismatch error and cannot proceed.

The Graphviz developers release a new development snapshot daily. I update the graphviz-devel port about weekly. To get these and all other updates, you do need to periodically run "sudo port selfupdate" or "sudo port sync" as Frank showed. Then you can use "port outdated" to see what's outdated, and "sudo port upgrade" to upgrade any or all of those ports.
