bundle install libv8 keeps loading for ages

So I'm trying to install libv8 (3.11.8.17) that is a dependency of
therubyracer on Mac OS Mountain Lion. However it keeps loading for
ages.... Saying:
Installing libv8 (3.11.8.17) with native extensions
Didn't work:
uninstalling and installing libv8
brew install v8 and then installing libv8
downgrading therubyracer
