spec/rake/spectask error

I get the following error when running rake or rake spec:

Ah - this'll definitely be a bug with what version of rspec I'm requiring. I think I have it set to require >1.something, but 2.0 broke compatibility, so it should be ~>1.something. I have a few projects that'll need to be migrated – thanks for the tip!

A more appropriate explanation has provided with commit 67e8389.

Just a question, how can I download RSpec 1.x and overwrite 2.x with it? Or, even better, install both versions side-by-side?
