Pod build fails - unknown option character `X' in: -Xlinker

[yelled3]

I installed the pod using:

pod 'BrightFutures', :git => "https://github.com/Thomvis/BrightFutures.git"

when building the project I get:

(null): /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: unknown option character `X' in: -Xlinker

I'm using Xcode 6.1.1 (6A2008a)
For the time being I just embedded BrightFutures in my project, without cocoapods :-/

Anyone?

Please make sure that you're running the latest CocoPods beta: 0.36.0.beta.1. You can check this by typing pod --version.

If you're not running the beta, use gem install cocoapods --pre to upgrade to the beta (at your own risk ;))
