NotImplementedError on Ruby 2.1

[indirect]

Bundler runs its spec suite against ruby-head, and this error just started appearing on ruby 2.1.0dev (2013-10-22 trunk 43390) [x86_64-linux].

We don't do anything that non-standard with inspect and this:
T_NODE object (0x00000001759418 flags=0x15281c klass=0x0) (NotImplementedError)
makes me think you may have found a Ruby bug.

If this is still happening in the 2.1.0 RCs we'll certainly take a look.

@myronmarston I'll throw 2.1 into the travis.yml and see what happens :)

This is a ruby bug that I reported and got promptly fixed:
