^ Nathan did mention earlier in the thread that he "had to install
libtinfo5 and libc++1-7 on Debian Buster." Emphasis on the _and
libc++_ part.

I'm not sure if that binary distribution came with a libc++.so.1; if
so, that path needs to be specified via LD_LIBRARY_PATH so that the
runtime loader can find it. Perhaps rpath wasn't set when the clang
binary was built.

We're looking into statically linked images of clang to prevent these
kinds of games.
