it took a few more steps to get sbuild to get over missing dependencies...i had to go into the chroot again, import repo keys or it wouldn't let me execute apt-get update.
apt-get update was needed to resolve some more dependencies where packages presumedly changed in the middle of my chroot installation.
checking for llvm-config... not found
ERROR: Could not find LLVM/Clang installation for compiling stylo build-time
bindgen. Please specify the 'LLVM_CONFIG' environment variable
(recommended), pass the '--with-libclang-path' and '--with-clang-path'
options to configure, or put 'llvm-config' in your PATH. Altering your
PATH may expose 'clang' as well, potentially altering your compiler,
which may not be what you intended.
