Unable to launch rails due to "'executable-hooks (= 1.6.0)' (Gem::UnsatisfiableDependencyError)"

Have had this error for a couple of weeks now and keep giving up trying to solve it, forget about it and then rediscover it. The cycle of pain has been killing me.

I've tried completely purging ruby version manager(rvm), reinstalling bundler, xcode, openssl amongst other things. Could this potentially be a $PATH problem? Really clutching at straws here.

Thanks for your time.
