I was able to get istgt working on my Mac host. Using the in-kernel initiator on NetBSD, I’ve run a cvs update on a netbsd-6 source image and rebuilt everything without any problems.

BTW, the istgt code in pkgsrc uses an initialized mutex, which apparently works on BSD but causes an error on MacOS. The attached patch appears to work.

You’re right. No idea how I concluded otherwise.

Thanks for your help!
