What are versions of items in vendor/plugins?

Hello all,

I'd like to figure out what version of RSpec is in this Rails' project's vendor/plugins/ since they were frozen some time ago - I just don't know when which became apparent when setting up a new dev box and running tests using 'spec' has failures over-and-above running all tests with 'rake'.

Unless there's a way to have the app 'spec' use a Rails project's vendors directory - or any other work-around, really.

Thanks!
