M1macでbrew install circleci でこけるときはcurlだ！

M1 mac だわーい。と意気揚々とセットアップしてたら、circleciでつまった。

brew install circleci だとエラーくる。。。。
かなしい。。

You can try to install from source with:
  brew install --build-from-source circleci
Please note building from source is unsupported. You will encounter build
failures with some formulae. If you experience any issues please create pull
requests instead of asking for help on Homebrew's GitHub, Twitter or any other
official channels.

しらべていくと、githubに同志発見。
