This is probably because its usage of startupitems needs to be adjusted to match the new requirements of MacPorts 2.6.3, similar to the way I did it for adblock2privoxy in ​https://github.com/macports/macports-ports/pull/7892.

I started to try to do it for clamav-server, but the way that it uses startupitems is really very difficult to deal with and I could not persuade myself to finish wading through it. I encourage you to find a more legible and maintainable approach, such as putting scripts into their own files.
