Since I pulled a new update, I could not install anymore.
Then I tried to do a fresh start as much as possible. Updates all homebrew dependencies, re-cloned the repository, checkout out at the latest stable version and tried to build from scratch.
I got the following error, it really looks like the one I got before the fresh start, but I'm not certain it is the same: https://gist.github.com/stevenroose/7109724
Anyone experience with this?
