I can't explain this -- why does globally installed gem with script fail in a directory with a Gemfile?

I have a gem installed system-wide called `scrapers` that has a binary
called `rubytapas`. It will run nearly everywhere *except* within a
directory that contains a Gemfile.

It can be a completely empty directory otherwise, and the Gemfile can
be empty. It still fails by getting confused about finding
dependencies.

The gist https://gist.github.com/tamouse/9822711 shows what is
happening, I think.

And I have the answer, just another stupid mouse trick.

I had:

require 'rubygems'
require 'bundler/setup'

at the top of the bin file, so it was doing exactly what I told it to,
instead of what I wanted to have it do.

Looks like a useful gem.
