Yeah, I've been using the apt.llvm.org to build most of the clang docker
images. Unfortunately it doesn't include the libc++ packages, I've e-mailed
the guy who builds the packages (also the debian libc++ packager) to see if
that could be in the cards.

If those ducks can get in a row, that would be my preference, but failing
that, I may just move to grabbing those binaries from the releases section.
That seems like it would be about as easy, and works now.
