`bundle check` always fails (and why do we even need this extra step?)

What does this check in bundler.cap (like 31) do

```
unless test(:bundle, :check, *options)
```

This is always returns false for me and therefore bundler:install gets skipped.

Read bundler.cap around line 31, starting with the `test(:bundle, :check, *options)` condition, and reproduce the reported behavior. Trace how that result controls `bundler:install`; done means the check's purpose and failure are understood and the install step is no longer skipped incorrectly.
