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!
