Currently, the lockfile gets printed after `bundle install` finished. This could be too late when `bundle install` fails for whatever reason.
I have a workflow that failed like this:

It would help to print the lockfile for this I think. It fetching version 0.0.1 confused me but probably the lockfile looks ok. New output:
```

So it's relatively at the top and not hidden somewhere. Also removes the need to check for the lockfile again.
* And give instructions for that case.
* Get the OS and OS version ourselves since some users set ImageOS incorrectly.
* This partially reverts commit ad1ebae995.
* On Windows there are no 64-bit builds of Ruby 1.9.
* Fix floatVersion() for head versions.
* Use floatVersion() in more cases instead of regexps.
* Rely on ~/.gemrc to not install gem docs.
