I tried to build native app for Android with sencha command but has no success. I got a error:

[INFO] Packaging your application as a native app...
[ERROR] /bin/sh: 1: stbuild: not found

I tried to find this utility ("stbuild") in Sencha SDK Tools, but it's not there.

My environment is:
- Ubuntu Linux 12.04 (x64)
- java version "1.7.0_04"Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)
- Latest Android SDK
- Sencha Touch SDK 2.0.1
- Sencha Touch SDK Tools 2.0.0 Beta 3
