Over on the UNCENSORED Citadel (at https://uncensored.citadel.org/ ), I made a post with my work getting Citadel and its tools to compile on FreeBSD.  Unfortunately, I had not actually run it, so there are some outstanding issues that remain unaddressed.  I am working on this.  If you are reading this on Killer Kittens (my Citadel at https://ladyserenakitty.com/ ), then you already know I did actually get Citadel running on FreeBSD.  Yay!
