Homebrew doesn't know what compiler versions ship with your version
|
|
of Xcode (#{Xcode.version}). Please `brew update` and if that doesn't help, file
|
|
an issue with the output of `brew --config`:
|
|
https://github.com/Homebrew/homebrew/issues
|
|
|
|
Note that we only track stable, released versions of Xcode.

Thanks!
