More comments on my nufraw thread, TLDR version is that I had to include iostream to even get close to the problem with 0.27.0 (might be a gcc-8.3.0 issue. The rc did not solve that problem, but adding a ufraw patch from gentoo allowed me to build it, so my problem has gone away.
Calling it 0.27.1.1 for an -rc seems weird, but on the bright side the mac dotfiles are gone (I see the issue is still open).
