      system "xcodebuild", "-target", "AquaTerm", "-configuration", "Default", "LOCAL_FRAMEWORKS_DIR=#{frameworkpath}", "LOCAL_APPS_DIR=#{apppath}"

      apppath.install       'build/Default/AquaTerm.app'
      frameworkpath.install 'build/Default/AquaTerm.framework'
    end
    sharepath.install 'adapters'
  end

  def caveats
    # the same for AquaTerm.app?
    framework = prefix + "Library/Frameworks/AquaTerm.framework"
    if self.installed? and File.exists? framework
      return <<-EOS.undent
        AquaTerm.framework was installed to:
          #{framework}

        You may want to symlink this Framework to a standard OS X location,
        such as:
          ln -s "#{framework}" /Library/Frameworks
      EOS
    end
    return nil
  end
end

I tried to use your formula in Mountain Lion.

I got this problem (below).

How you fix this?

Thanks.
