Cannot use MonoTouch in Portable libraries in Xamarin Studio

Question

I installed Xamarin & XamarinStudio on Win7 x64 and I am able to build and test (on emu) basic android apps.

But when I'm trying to create C# Portable Class Library there is no checkbox for Android or iOS. Screenshot attached.

Could you help please?

http://docs.xamarin.com/guides/cross-platform/application_fundamentals/pcl/introduction_to_portable_class_libraries/-使用本文的说明，尤其是我需要在命令提示符下运行PortableLibraryTools.exe / buildmachine，然后重新安装整个Xamarin。
