Cordova 5.1.1 - Installation Issue

I am unable to install the plugin via plugman on cordova 5.1.1.

Here's my error.

cordova create hello com.example.hello HelloWorld
cd hello
cordova platform add ios
sudo plugman install --platform ios --project . --plugin https://github.com/phonegap-build/GAPlugin.git

Same issue occurs at Phonegap Build service when using CLI 5.1.
