This looks to me like you are using an older example. I think that's how you used to do it about a year ago. Back in late 2012 that method of setting up the app was deprecated because Signet was updated to handle all aspects of the OAuth2 setup.

Here is the code I generally use to create a service account. You can tweak it to fit into your method.

client.authorization = Signet::OAuth2::Client.new(
 :token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
 :audience => 'https://accounts.google.com/o/oauth2/token',
 :scope => "https://www.googleapis.com/auth/drive",
 :issuer => "@developer.gserviceaccount.com",
 :signing_key => Google::APIClient::KeyUtils.load_from_pkcs12("-privatekey.p12", "notasecret"),
 :person => "")
client.authorization.fetch_access_token!

If you are still having issues let me know and I'll see if I can help.
