V2,3,3,1 bugfix

And already we have a bugfix release. There were three of them.

The first was a failure to test a headless build and there was a detail we'd forgotten.

The second was not accounting for some less common build environments.

The third was a total surprise. It was a bug in effects that goes back at least 6 years and probably further, but only became obvious with the latest EQ display improvements we had made.
