This seems to be because Homebrew tests for an empty installation, and it's looking in /usr/local/Cellar/grantlee/0.5.1 which only gets so-called "metafiles" like AUTHORS and README. Homebrew doesn't count these as real files, and concludes nothing was installed and errors out.

Adding a dummy file in the formula to be installed would get around this.

A hackish way to do this would be to manually disable this checking functionality in Homebrew itself.

# /usr/local/Library/Homebrew/keg.rb
def empty_installation?
  # HACK: ignore "empty installations"
  return false

  Pathname.glob("#{path}/**/*") do |file|
    next if file.directory?
    basename = file.basename.to_s
    next if Metafiles.copy?(basename)
    next if %w[.DS_Store INSTALL_RECEIPT.json].include?(basename)
    return false
  end

  true
end
