Ran into issues trying to run dragonruby-publish to publish one of the sample dragonruby apps as a test. Any help would be appreciated. I can launch the sample app with dragonruby just fine.
$ ./dragonruby-publish mygame
Starting publish for game in directory 'mygame'
Developer ID: myname

I've installed butler via the Itch app (https://itch.io/docs/butler/installing.html), and also dragonruby, but using the downloaded binary to try to publish.
