Can not install substrate on emulator

I'm trying to install cydia substrate on emulator, when I try to link substrate files I got multiple errors,

Then I replaced /system/xbin/su with a suid-ed /system/bin/sh file and disabled SELinux with setenforce command.

But I still got this:

Anyone know what should I do? With adb shell I can get root but I don't know what script to run ....
