Build fails for android on mac os x

Hi, I am trying to build for android on mac os x. I followed the build steps in the wiki as follow:
1. boot strap for mac os x (success)
2. full build for mac os x (success)
3. boot strap for android (success)
4. full build for android (failed)

Here is the output log

I read on the troubleshooting section and tried the buildone command, but it gives the same error.

Is there something wrong with my command? Or am I missing any steps which causes this problem?
Before doing this build, I have also ran these commands and I can see the soft links of dist in my cerbero folder.

sudo mkdir /Library/Frameworks/OpenWebRTC.framework
sudo chown $UID /Library/Frameworks/OpenWebRTC.framework/
In ~/cerbero:

mkdir -p dist
mkdir -p /Library/Frameworks/OpenWebRTC.framework/Versions/0.1
ln -s /Library/Frameworks/OpenWebRTC.framework/Versions/0.1 dist/darwin_x86_64

Start by reading recipes/openwebrtc.recipe around line 191 and the config/osx-x86-64.cbc and config/cross-android-armv7.cbc entry points. Reproduce the sequential buildone commands, then verify that the Android package command completes without the host-darwin error.
