I compiled these in Debug mode on macOS 10.15.3, using this Xcode project. If you just need the PublicUtility library then go for it. However I do encourage you to build from source as these things are pretty archaic and probably need to be tweaked in some way, depending on your own code.
libACPublic.a, libAFPublic.a, libAUPublic.a and PublicUtility should cover all your needs. If you want the individual bases in AUPublic I've put them in the separate-au folder in the zip.
