Ruby on Rails

Some background:

I set up my first rails app for testing with rspec, and everything
worked fine: I could run tests, etc. Then I created a second rails app
to play around with (and a third, fourth). But I can't get testing to
work with my second rails app. When I cd'ed to my second app's
directory
and did this:

$ bundle exec rspec spec/

it ran the tests for my first app. My first app has about 150 tests,
and my second app has 3 tests, so it was obviously not running the
correct tests. In an attempt to cure that problem, I did took these
steps:

1) I closed out all windows on my computer.
2) I restarted my computer.
3) I opened a terminal window and cd'ed into my second apps directory,
and then I did this:

$ bundle exec rpsec spec/

and I got this error:

No DRb server is running. Running in local process instead ...
