Twitter recently tightened restrictions on OAuth. From the discussion (https://dev.twitter.com/discussions/16443):

You must pass an oauth_callback value to oauth/request_token. It's not optional. Even if you have one already set on dev.twitter.com. If you're doing out of band OAuth, pass oauth_callback=oob.
You must pass along the oauth_verifier you either received from your executed callback or that you received hand-typed by your end user to oauth/access_token.

Long story short: You must update ShareKit from the master branch, or at least pull this commit: https://github.com/ShareKit/ShareKit/pull/692
