brew install throws error

[tthil]

After brew tap cuber/homebrew-libsecp256k1 the brew install libsecp256k1 throws an error.

Error: An exception occurred within a child process: MethodDeprecatedError: Calling BuildOptions#universal? is disabled! There is no replacement. Please report this issue to the cuber/libsecp256k1 tap (not Homebrew/brew or Homebrew/core): /usr/local/Homebrew/Library/Taps/cuber/homebrew-libsecp256k1/libsecp256k1.rb:15

The same issue for me, executing brew install --debug libsecp256k1 produces (extract):
