Comment (by neverpanic):

 The website update system may be broken at the moment, I'm not sure of the
 current status.

 You cannot specifically select which version to install – MacPorts will
 always install the latest version it knows about. As long as `port info
 ghostscript` does not show `9.21_1` (but `9.21_0`), installation will
 fail. The fix was committed yesterday, but our rsync infrastructure that
 updates the set of publicly available ports has been a little slower
 lately, so please allow up to 24h for the change to show up.

 If you want this to happen faster, you can use wiki:howto/SyncingWithGit
 at the expense of more CPU usage because you will have to generate a
 portindex locally.
