Build fail for iOS triggered by nativeutils

I’m trying to build my project for iOS, but this fails. Last time I built my project, though this is a few months ago, there were no problems. I am now using the latest version of Meteor, 2.5.1.

When running meteor run ios-device, I get this:

**While adding plugin https://github.com/pmwisdom/NativeUtils.git#64460ce4e28a346245beb2c5a7413bd67a6c148d to Cordova project:**

**Cordova error: Failed to fetch plugin https://github.com/pmwisdom/NativeUtils.git#64460ce4e28a346245beb2c5a7413bd67a6c148d via registry.**

**Probably this is either a connection problem, or plugin spec is incorrect.**

My connection seems fine, I can access the project on GitHub. I do not call this package/plugin directly. So, how do I resolve this?
