Instalación de Android SDK más antiguo con Homebrew

Estoy intentando instalar Android SDK versión 21

android-sdk git:(master) ✗ brew versions android-sdk Warning: brew-versions is unsupported and will be removed soon. You should use the homebrew-versions tap instead: https://github.com/Homebrew/homebrew-versions 24.1.2 git checkout bd7fe0a /usr/local/Library/Formula/android-sdk.rb 24.0.2 git checkout 9bae1ec /usr/local/Library/Formula/android-sdk.rb 24.0.1 git checkout dfc52fa /usr/local/Library/Formula/android-sdk.rb 24 git checkout 9c59883 /usr/local/Library/Formula/android-sdk.rb 23.0.2 git checkout 40a85ed /usr/local/Library/Formula/android-sdk.rb 23.0.1 git checkout dafcd64 /usr/local/Library/Formula/android-sdk.rb 23 git checkout fc9b23b /usr/local/Library/Formula/android-sdk.rb 22.6.2 git checkout b40ef74 /usr/local/Library/Formula/android-sdk.rb 22.6 git checkout 21a3ec9 /usr/local/Library/Formula/android-sdk.rb 22.3 git checkout 05c8367 /usr/local/Library/Formula/android-sdk.rb 22.2.1 git checkout a8e49e1 /usr/local/Library/Formula/android-sdk.rb 22.2 git checkout 65aa6b0 /usr/local/Library/Formula/android-sdk.rb 22.0.5 git checkout 1b2c080 /usr/local/Library/Formula/android-sdk.rb r22.0.4 git checkout 758cbf0 /usr/local/Library/Formula/android-sdk.rb r22.0.1 git checkout 33258e5 /usr/local/Library/Formula/android-sdk.rb r21.1 git checkout c150b7e /usr/local/Library/Formula/android-sdk.rb r21.0.1 git checkout 5909091 /usr/local/Library/Formula/android-sdk.rb r21 git checkout 276fd63 /usr/local/Library/Formula/android-sdk.rb r20.0.3 git checkout 1d90e9d /usr/local/Library/Formula/android-sdk.rb 

Luego, para instalar la versión 21

 git checkout 276fd63 /usr/local/Library/Formula/android-sdk.rb android-sdk git:(master) ✗ brew install android-sdk 

Pero consigo el error siguiente
