DRb::DRbConnError

Hello, I am trying to run my tests using rake, but I keep getting this
error. Anyone know why that might be happening?

Does your app make use of drb in any way ?

I'm using backgroundrb, but I have removed all of my tests except for
one as I am rewriting them to make them even more thorough. The test
that I am trying to run does not use backgroundrb.
