Rails 4 will not run (under rbenv); pathname problem with app_rails_loader

[Matthew Davis]

This is an OS X Homebrew install, with rbenv root in /usr/local/var/rbenv; Ruby 2.0.0, and Rails 4.0.0.  'gem install rails' went without complaint. Then I tried to run 'rails new hypothetical_app'. That, and all calls to the rails app, show that app_rails_loader is finding a directory bin/rails where it expects to find a file bin/rails:

Aside from not setting my rbenv root to ~/.rbenv, I can't think of any departures I have made from completely standard installation of everything.

So, I just did this on a brand new machine, but using rvm instead of rbenv. No problems on this end. I'd be looking at the rbenv configuration.
