Mac mini（Catalina）に Jubatus をインストール。「brew install」の方でエラー「invalid option: --use-clang」

引き続き、管理者権限のあるユーザで以下を実行
$ brew tap jubatus/jubatus
$ brew install jubatus --use-clang

後者で、エラー。
Error: invalid option: --use-clang

そんこと言われても、Jubatusのページのリンクから、インストールはそうせい、と書いてある・・・。

Usage: brew install [options] formula

Install formula. Additional options specific to formula may be appended to
the command.

Unless HOMEBREW_NO_INSTALL_CLEANUP is set, brew cleanup will then be run for
the installed formulae or, every 30 days, for all formulae.

-d, --debug If brewing fails, open an interactive
debugging session with access to IRB or a
shell inside the temporary build directory.
--env If std is passed, use the standard build
environment instead of superenv. If super
is passed, use superenv even if the formula
specifies the standard build environment.
--ignore-dependencies An unsupported Homebrew development flag to
skip installing any dependencies of any
kind. If the dependencies are not already
present, the formula will have issues. If
you're not developing Homebrew, consider
adjusting your PATH rather than using this
flag.
--only-dependencies Install the dependencies with specified
options but do not install the formula
itself.
--cc Attempt to compile using the specified
compiler, which should be the name of the
compiler's executable, e.g. gcc-7 for GCC
7. In order to use LLVM's clang, specify
llvm_clang. To use the Apple-provided
clang, specify clang. This option will
only accept compilers that are provided by
Homebrew or bundled with macOS. Please do
not file issues if you encounter errors
while using this option.
-s, --build-from-source Compile formula from source even if a
bottle is provided. Dependencies will still
be installed from bottles if they are
available.
--force-bottle Install from a bottle if it exists for the
current or newest version of macOS, even if
it would not normally be used for
installation.
--include-test Install testing dependencies required to
run brew test formula.
--devel If formula defines it, install the
development version.
--HEAD If formula defines it, install the HEAD
version, aka. master, trunk, unstable.
--fetch-HEAD Fetch the upstream repository to detect if
the HEAD installation of the formula is
outdated. Otherwise, the repository's HEAD
will only be checked for updates when a new
stable or development version has been
released.
--keep-tmp Retain the temporary files created during
installation.
--build-bottle Prepare the formula for eventual bottling
during installation, skipping any
post-install steps.
--bottle-arch Optimise bottles for the specified
architecture rather than the oldest
architecture supported by the version of
macOS the bottles are built on.
-f, --force Install without checking for previously
installed keg-only or non-migrated
versions.
-v, --verbose Print the verification and postinstall
steps.
--display-times Print install times for each formula at the
end of the run.
-i, --interactive Download and patch formula, then open a
shell. This allows the user to run
./configure --help and otherwise
determine how to turn the software package
into a Homebrew package.
-g, --git Create a Git repository, useful for
creating patches to the software.
--enable-mecab jubatus: Enable mecab for Japanese NLP
--enable-zookeeper jubatus: Enable ZooKeeper for distributed
environemnt
-h, --help Show this message.
