Is it possible to use an HTTP proxy with capybara?

Capybara's API doesn't seem to support configuring an HTTP proxy. Is there any way to use one with it? Context: I'm using capybara with cucumber to test a rails application, and akephalos as the javascript driver. There's a script tag on the page that makes a request to an external site (in this case, maps.google.com). The cucumber test fails with the following message: org.apache.http.conn.HttpHo
