Comment (by Ionic):

 I could have released the update today, if life were easy.

 Sadly, it's not. Apple's new implementation of the keychain integration
 depends upon new features in their `Security` framework, including, what
 seems to be, a private header. I don't know if that's even installed on
 user systems.

 I wasn't able to find a file called `SecItemPriv.h` anywhere within
 `/System/` on a 10.13 box, but Apple's openssh implementation uses it.
 They probably can do this because they have special SDK/Frameworks and
 build everything in an Xcode environment, but for MacPorts, that behavior
 is not ideal.

 I'll need more time to figure out what to do. Maybe I can ship shim
 definitions just for the needed parts, but I'll have to see whether the
 `Security` frameworks (esp. on older platforms) even provide the needed
 functionality. If not, I'll have to revert the patch to an older,
 pre-`Security`-framework version and adapt it myself.
