Chruby Doesn't Support Binstubs

[joseph-ravenwolfe]

Chruby's auto.sh does not add the ./bin to $PATH when a .ruby-version file is encountered.

It appears the Rails team and Rbenv contributor prescribe that it is the responsibility of a ruby version manager to provide this functionality so that binstubs may be used as expected.

Is this currently not supported in chruby for a philosophical reason? Pull request to come if this is an acceptable feature.

Always trusting and prioritizing ./bin/ over /usr/local/bin:/usr/bin is a security risk. Binstubs are the responsibility of bundler, not chruby.

[postmodern]

Forgot to mention that the Bundler developers prefer that people explicitly choose between foo and ./bin/foo. However, you can install the rubygems-bundler plugin that will always execute the bundled version.
