Look at build [Build/Requirements]. Some of those programs you can build
with the help of contrib/prepare-deps scripts. Both master and slave
nodes most likely will require [CI/Daemontools]-like solution also, but
you should be able to build it by BASS build system itself and install
using it in [Build/skelenv].

Currently a heavy work in progress, especially related to CI-part of the
project (package building/management is pretty steady now).

    $ git clone git://git.cypherpunks.su/bass.git
    $ cd bass/contrib/prepare-deps
    $ ./dl
    $ ./do
    $ PATH="$(realpath local/bin):$(realpath local/go/bin):$PATH"
    $ cd ../../build
    $ echo SKELBINS=/tmp/skelbins >rc
    $ export BASS_RC=$(realpath rc)
    $ pkg/mk-arch
    $ redo pkg/FreeBSD-amd64-13.2-RELEASE/shells/zsh-5.9
    $ cd /tmp
    $ mkdir myskelenv
    $ cd myskelenv
    $ /path/to/bass/build/bin/mk-skelenv
    $ /path/to/bass/build/bin/pkg-inst shells/zsh-5.9
    $ . ./rc
    $ zsh
